Bogdan, your videos are always high quality and educational. Thank you. I have bought many items based on your recommendations and am very happy. For instance, I now have the full Morpheus collection and couldn’t be happier. Also I purchased the Baader T2 prism diagonal for my Skymax 102 and enjoy that. You are making a difference. Keep it up. Best wishes from Canada.
Outstanding video, excellent for newcomers and veterans alike. I would mention an extremely long relief eyepiece for your viewers. This is the TeleVue 55 mm Plossl (price in the U.S. $256). At a 50 degree field of view it isn't in direct competition for wide angle eyepieces. But its quality is superb, its price is reasonable, and it is excellent for SAFE Solar viewing through the well-regarded DayStar Quark Hydrogen Alpha filter. This is because the DayStar contains a 4.3 internal Barlow lens. Your 600 mm refractor becomes a 2064 mm solar telescope. The 55 mm Plossl gives you a good view of the sun at a magnification of 37.5 times. This is a specialized use of the eyepiece, but when viewing the sun you don't have to worry about light pollution, and the sun is a dynamic object, constantly changing. These are just some thoughts.
@JamesAdams-ev6fc Thank you for your feedback! Even though the Plössl's optical design has some limitations like the narrow FOV, they can certainly deliver some excellent views of the night sky, especially the ones from Tele Vue. I hadn't considered them for solar observations, but I agree, they can be great for that application as well.
Glad that I could be of service.. Your videos are fun, educational and I find your observations to be highly accurate. You must be in engineering. @@BogdanDamian
@@BogdanDamian Hi Bogdan !! Well TBH i ❤ the T2s so much i never tried the other variants. I am probably alone in feeling that the summit of the 20mm & 12mm optical Perfection was replicated in the T5 20mm discontinued now fl. I respect the ludicrous weight of it so when serendipity knocked with Pristine used examples i tried to not have super light and super heavy so made all of them somewhat heavy. I could regale you with tales of how Insane the Views for hours. 12mm T2 33.3X got E & F star trapezium with my Superb 62mm apo Evolux. I never suspected the Thousand Greys and dozens of nuanced blacks on the lunar surface at its 33.3X power and the 20mm in my 100mm F/9 is 45X and 16.5XW 54.5X for DSO nuancing. The 20mm seems like 100degrees I just don't know how Mr. Nagler achieved that trickery or perceiving at 75X 12mm T2 luna is Spherical in nature....sublime. Clear skies BD observatory I dream of that
@palmereldrich Hi! That sounds really great, thanks for your input! I will try to get my hands on the T5 20mm as I heard from other sources as well that those eyepieces are fantastic. Clear skies!
Thanks Bogdan! I worked hard to afford some Televue Plossls and a couple Delites. I'm not sure if Televue eyepieces are really worth the high price, but everyone swears by them. I agree that wide-field views aren't worth the cost of large, heavy and outrageously priced eyepieces. My Delites are fine, but I think it would have been better to get less expensive Plossls instead. I just want great optical performance. I"ve said this before, but for planetary viewing with my f/7.4 100mm refractor, nothing else beats the Takahashi TOE eyepiece. I'm not happy to recommend such an ultra-expensive eyepiece, but I think the TOE is worth buying if you want the best possible planetary detail in a 4-inch refractor. I was using a Televue 8mm Plossl with a 2x Barlow for the planets, but the Takahashi is noticeably better.
@vampolascott36 Thanks for your input. Tele Vue eyepieces sure are expensive, but they are very good and also represent a good investment since they hold on to their price for decades. I didn't had the chance to test the TOE yet, but I'll try to change that in the future and maybe make a video about it. Clear skies!
13:10 eyeglass wearers just be warned that the stated 22mm eye relief on the explore scientific 30 82 is not eyeglasses friendly because of how deeply recessed the lens is into the eyepiece. The effective eye relief is MUCH less. Still a beautiful and easy to clean (waterproof) eyepiece if you don't wear glasses.
Thank you Bogdan! I must say I like your style and the way you clearly explain the features, pros and cons of astronomy equipment to the benefit of others who can't afford to buy lots of stuff to try out. Your insights really help a lot! So thanks 😉
Great video Bogdan! You're educational guide helped me choose a good and budget friendly eyepiece. I recently got a Hyperion 24 mm and I'm very happy with the results. Thank you so much! 👍
Enjoyable video. I have baader zoom 8-24 then bought baader Morpheus 6.5, 12.5 and 17.5. Now I barely use the zoom! I’d like a top quality low power one day and will probably complete my Morpheus collection. Just wish I was as rich as you! 😅
High quality/sharp "glass" is certainly addictive. Getting 12.5mm Morpheus made 400 $/€ level APM (/SkyRover) 7.7-15.4mm zoom step above Baader Hyperion zoom feel totally mediocre. You might want to keep eye on Baader prices in case they expand "annual" discounts from Hyperion to Morpheus: After getting 12.5mm from "nearby" shop's relocating discount in last April Baader had (for the first time) 20% discount on Morpheus line in May and got others for €220. (including 24% VAT)
I like using a 100 degree eyepiece while viewing the planets because I can get most or all of the moons into the view as well. But that's just me. I use Ethos for medium (
The large and heavy ES eyepieces are great on refractors with heavy prime lenses up front where they look goofy slid well back into their rings when not laden with accessories near the visual back. With the heavier equipment mounted behind the mount's polar axis, you can slide the refractor well forward for a more esthetic look and more ergonomic eyepiece placement when the scope is aimed closer to the zenith.
Excellent video! A succinctly presented, categorized, cost/benefit analysis is exactly what is needed for making decisions with so many options. Thank you!
Excellent video. It would have also been interesting to see a category with cheap eyepieces :). Many amateurs like myself payed 200-500 euro for the telescop so 200-300 euro for an eyepieces will be too much.
Agree, similar for anyone got a deal on a used scope in same price range. Was lucky scored a dob 8 inch for half price and within driving distance pick up so no shipping cost too
Thank you for this video! Your expertise has grown a lot. I appreciate the large list of eyepieces for each category, and that the categories and brands are consistent. Finally I have the information I need to buy a wide-angle, long focal length eyepiece. It's gonna be an Omegon 32mm. If you still like it after using the Televue, surely it's good enough for me.
Thanks for the great overview. This really makes me -again - think of replacing my Baader Hyperion with some Morpheus eyepieces. Or maybe a Delos in the near future. 👍
@stefanfeichtenbock6949 Yeah, the Delos eyepieces are excellent, but also very expensive, especially here in Germany. For half their price you can get a Morpheus eyepiece which is capable of a similar optical performance. This is how I would choose anyway. Clear skies!
The Explore Scientific 12mm 92 deg, the 17mm 92 deg, and the 28mm 68 deg get very strong support when eyepieces in the premium range are discussed. Also, the Nagler T6 31 mm.
I have it. It was second eyepiece after 28mm UWA "hand grenade" I got for my "small" upgrade from 110mm TAL-1. (250mm f/4.8 light bucket) Then getting Baader Morpheus 12.5mm made it feel plain mediocre. Sure it's possible that mine is below average "sample". But propability is for it being average and expecting it to compete against high quality eyepiece in any way being just too much.
I discovered the Masuyama brand (made in Japan) which makes lenses for many pro cameras (Nikon). Check this one out: MASUYAMA 1.25″ Series 85° (US$ 229) at AstroHutech).Focal length : 16mm Apparent field of view : 85-degree Eye relief : 10.0mm Field stop : 23.5mm Lens configuration : 5 elements in 3 groups Coating : fully multi-coated Physical length : 68mm Outer diameter : 41.5mm Weight : 138g
It's basically meant for f/10 and slower. Five elements isn't even remotely enough to correct aberrations of such AFOV eyepiece well for use in fast telescopes. Also 10mm eye relief is really short for the AFOV.
Very informative video....I do have the 2" Omegon 32mm ...purchased from your recommendation....its my goto ep to start the night. I also have svbony 26mm and skyoptikst 15mm ,which both I like. I did purchase the 2-1.25 Omegon 7mm ..but also purchased recently Explore Scientific 2" 9mm...which I enjoy very much....keep up the great videos.
another nice video Bogdan. As I decided for the Svbony 107 ED I did flirted a bit with the Baader Zoom as a first eyepiece. Since I can get the SvBony Gold line 66degrees (6mm, 9mm, 15mm, 20mm) for 99EU I think I will get them and experiment with all before moving to more expensive stuff. I admit however if I spot a deal in EU or US for Morpheus 17.5mm I will jump on it, the big lens with wide field of view make it really attractive for glasses, hopefully it will be my main eyepiece offering 2.5 exit pupil.......but what am I saying here, first let's experiment with the gold line. I am however intrigued by the Hyperion which is on sale now in EU for 120EU , some say it needs to be opened and cleaned after one year (Morpheus is sealed even if is not actually water-resist like ExploreScientic)
@PauI__ Thank you! Never hared about Hyperions needing so much maintenance. I wouldn't worry about it. 120 Euros is a very good price for these eyepieces. They are totally worth it.
I'm surprised that nobody ever mentions the fine tuning rings for the Hyperion eyepieces in their videos. Personally, I think they are one of the strongest selling features of the series for people on a tighter budget. If you get a 13mm and 21mm Hyperion with the 14mm and 28mm tuning rings you essentially have 8 focal lengths ranging from 8 to 21 to play with for roughly $400 (9 if you remove the bottom lense off the 21mm and use it as a big 2" 32mm plossel). That's fantastic value in my opinion and you would be hard pressed to find a better deal.
Thank you for this very informative video! I'm learning new concepts everyday, because aside from the field of view angle, I have never considered its flatness as a factor. I'll certainly pay attention in the future. One quick question : There are no Celestron eyepieces in your list, and I'm not sure if I've ever seen one in some of your previous videos. Aren't they reliable and/or worthy ? The first eyepiece I bought after buying my telescope - the only one, so far - is a Celestron Luminos 7mm 82 degrees. I do like it but obviously, I don't have other brands to compare it to, yet.
@hellR1de Hi! I'm glad you enjoyed the video. I didn't include any Celestron eyepieces because the ones I tested so far weren't that convincing. But this is only my opinion and I didn't test all of them. For example I didn't had the chance to test the 7mm Luminos yet, so I don't know how good it is. The most important thing is that you like the eyepiece and enjoy the views through it. Clear skies!
@@BogdanDamian Totally right, thank you! I'm in fact, mostly curious about compairing them with a Tele Vue Delos or Nagler, with similar focal length. ;) To have an idea of how much a step up it is. I'm considering a Delos 4.5 or a Nagler 5, although it would push the limit with my Dobsonian 10" (254/1250), I guess...
Celestron doesn't really have anything remarkable for the price. (just like Meade... or SkyWatcher) For example that Luminos line has inconsistent quality/performance. Though 7mm and 10mm are good, but those are blinged up versions of UWAs with usually significant brand extra in price. Similarly Meade 5000 PWA serie is just brand overpriced Astrotech/SkyRover/Stellarvue/Tecnosky UWA made by Kunming United Optics.
@@hellR1de ~5mm eyepieces don't push anything in 10" Dobson itself. What they push is seeing. Exit pupil (Eyepiece focal length / Telescope focal ratio) is good for measuring how much you're pushing telescope/aperture. At highest have used 6.5mm Morpheus with 2x Barlow in my light bucket and that magnification is brutal for any issues in seeing. Morpheus would be excellent step up from UWAs with both very high quality, wide AFOV (mostly actually 78°) and good eye relief. Televue Nagler, which is actually "inspiration source" for UWAs, certainly has top quality, but as price of that small size has compromised eye relief. Delos line again has long eye relief, but AFOV is step down and size and weight is big.
What would be a good eyepiece for smaller children (5-12)to view through? In my experience watching small children trying to view through a telescope they mostly don't understand the concept of eye relief and like to put eye right up to the eyepiece. Keeping that in mind while still picking an eyepiece with good clarity and fov to give the best possible experience for the occasional viewing that children might have through the eye piece. My setup is a William Optics triplet, 81mm aperture, 486 focal length, f/5.9. What would you pick for something like this and those other considerations for DPO and Planetary? If you had to pick a couple . Thx
@Jdub8025 For children I would prioritize viewing comfort, which is why I would recommend a Hyperion or Morpheus from Baader or a DeLite/Delos from Tele Vue.
Why haven't you recommend the APM/TS Optics HDC XWA models? They cost almost the same as the Morpheus line and the 100⁰ that they offer are a completely different and awesome experience. I loved my Explore Scientific 14mm 82⁰ but when I tried the ES 14mm 100⁰ version, it just was on another ultra high category and replaced the 82⁰ immediately. For 250-310€, the XWAs are just awesome. Edit: if you haven't tried any of them, I recommend you to grab any of them! Edit 2: my current eyepiece collection, after tried +40 ep, including panoptics, Nagler, etc is: 30mm ES82 for big DSO, 14mm ES100 for DSO and moon, 14mm ES100 + 2X Barlow for moon and planets. I've recently also bought a 3-8mm Svbony as it was cheap for the 11/11 in AliExpress. Also own 8mm and 12mm BST Starguider models, as I prefer the 60⁰ fov for the moon and they're really well corrected.
@Testeriosandandroid1 Hi Juan! You guessed it right. I haven't had the chance to test the HDC XWA yet, but I'm planning on trying them out soon. Thanks for your feedback! Nice eyepiece selection you have there. Which 2x Barlow do you use with your eyepieces? Clear skies!
indeed apm 100 looks really interesting. My only concern is the eyeplacement would be difficult, short ER, Morpheus looks like it has a huge lens diameter and should be really confortable to look trough even for kids, I must get something to ease the view of my 6year old kid
@@PauI__ Morpheus is about the widest AFOV eyepiece line with good eye relief/relatively easy to see view. Already with 82° AFOV of UWAs and their typical eye relief you literally have to press eye close and start rotating head like peeking around the corner to see field edges. 100° AFOV would make it even harder and extra field would likely go completely unused by children. And just seeing same field as in Morpheus would be harder because of shorter eye relief.
@Bogdan what ware your most used eyepieces, I know it depends on what are you looking at but I think is interesting for begginers in your case with mak102 newtonian and 4inch refractor what ware the eyepieces that got the most use over time
@PauI__ My most used eyepieces are the 9mm DeLite, the 24mm Panoptic and the 32mm SWAN. In terms of zoom eyepieces I use the SV215 3-8mm zoom a lot when I want to keep things as simple and light as possible.
Hi Bogdan, thanks for another very informative video. I am very happy with Morpheus 6.5 mm for high power and Morpheus 14 mm for medium power observations! I get very sharp views thru both of them. I wonder if Morpheus lineup will have a low power EP in the future! At the moment, I am waiting for panoptic 27 mm for DSO observations! Panoptics (27 and 24) are difficult to get in the US, they are back-ordered everywhere :-(. If I can't get them in a couple of months, I will look into your other recommendations for low power EPs. Thank you!
Truly long focal length Morpheus would basically have to be different design and completely 2" size to fit needed field stop. Anyway AltairAstro/APM/SkyRover/StellaLyra/Tecnosky 30mm Ultra Flat Field would good be complement and is called as honorary Morpheus by some. (also used as complement to Delos line) 28mm UWA (Astronomics/SkyRover/Stellarvue/Tecnosky) would be even little wider "hand grenade" but with mediocre eye relief.
@@mthirugnana I have that 28mm UWA under Tecnosky brand bought from their "Christmas" discount year ago. Fits Pleiades, Andromeda Galaxy+its satellites really nicely into view in ~1200mm focal length telescopes. But seeing field edge needs pressing eye really close/"peeking around the corner". Also it's big and quite heavy. This is early version with later ones having conical top and smaller eyecup : ua-cam.com/video/GFRCQYgzOD8/v-deo.html
Hi Bogdan, I have recently bought Celestron Starsense 10'' dobsonian f4.7. It came with some cheap 25mm plossl. I am trying to pick eyepieces to replace the EP that my telescope was supplied with and buy some additional ones to cover the spectrum. WIth logic buy once, cry once and be done with it I am aiming at Tele vue range. Panoptic 24 or 27 (both sold out with delivery around April) and Delite for shorter focal lenghts. I live in Europe and away from the big cities. I was thinking 2-3 EP + barlow or 3-4 ep without barlow. Which focal lenghs would you recommend? Thanks
@peter5204 Hi Peter, first of all congrats on the new telescope! I would recommend getting the following focal lengths: 7mm, 24mm, and 30-35mm. A 2x 1.25" Barlow would make a lot of sense in combination with the first two focal lengths. If the Panoptic eyepieces aren't available new, then look at the used market as well. It makes sense especially if you have the possibility to meet with the seller in person and check the EP out before buying it. That is how I got my 24mm Pano.
@@BogdanDamian Thank you, recently I am starting to think whether I should have chosen 8'' version as that one has f6 therefore less demanging on eyepieces... I live in Switzerland and secondary market here is relatively small. Also prices here are much lower than in germany, closer to USD prices. For example Baader Morpheus costs here around 260.- and TV Delite around 290 , Delos 390, pano 24 370. With such a small price difference between baader (morph) and TV (delite), TV is better choice, right?
@peter5204 I envy the pricing over there :) The choice between the Morpheus and Delite boils down to the AFOV and the accessories ecosystem. In terms of image quality they are almost on the same level. At these prices I would personaly go with the Delite.
@@BogdanDamian well from germany that is not so far for shopping trip :) wider afov would be probably nice thing to have but arent the ep with wider fov more prone to coma effect? I have read and see like million posts, articles and videos. I am literally going nuts here :)
@peter5204 While a wider AFOV will show more coma it is negligible in high power planetary observations. Chances are you won't notice anything at all. In this case you only have one relatively big object that you follow across the fov. If you think you would enjoy a larger AFOV, then get the Morpheus and never look back. It's an excellent eyepiece.
Thank you for a fantastic video it's helped alot... I noticed you have a skywatcher skymax 102 Mak, I just got the same telescope on a AZgti mount, do you have any tips for the focuser, one little touch will make it wobble like crazy.
@Slipperyducker Glad you liked the video. Also congrats on your new telescope! Its definitely a good one. I assume you mean the telescope on the mount is wobbly and not the focuser knob itself, right? If yes, then responsible for the whole setup being wobbly is unfortunately the mount. The higher the center of gravity is the higher the instabillity. Try observing with you siting on a chair so that the mount doesn't need to be fully extended. Other than this and spreading the triod legs as much as possible, there isn't much you can do. The next step woud be to swithch to a more heavy duty tripod. The mount head should work in combination with any tripod on the makret. Hope this helps. Clear skies!
@@BogdanDamian Evening, sorry I should've gone into more detail 😅 the focuser knob isn't wobbly, what I find is as soon as you touch the knob to focus even ever so slightly it will move. But what you're saying explains alot the tripod that comes with the package is very lightweight, I will definitely try it at a lower setting. Clear skies.
Hyperion 24 sharp to the edge? Maybe at f10. The es68 24mm is much better in that regard. I replaced my 24 Hyperion with the earlier meade version 5k swa, and it was almost as good as the panoptic, and now i have the es68 version to replace it after my 24swa was stolen along wjth a bunch of other even more premium grade 1.25" that were in the same pelican style case with my televue pronto.
One thing you neglected to mention on the goldline (and also redline) eyepieces is that they are not great in fast scopes. Coma gets exaggerated very noticeably.
6mm and 9mm are well corrected for fast telescopes. (though 6mm has some issues in ghosting/eye psoitioning) But 20mm and especially 15mm are oldies from time when f/8 was fast telescope and have lots of astigmatism showing on faster telescopes. 15mm one basically shouldn't be used in faster than f/10 or it will shit itself.
@@tuunaes Actually, at F4, this scope isn't bad without a CC. I built it to travel and it's really compact, so I couldn't add the extra weight to it. The coma really isn't bad unless you use cheap eyepieces. When I tested the 9mm, the coma was 2-3 times worse than my APMs. Orion also makes a 25mm that isn't bad in this scope as well. I would hesitate to buy these eyepieces faster than F5 (or maybe even at f5, as I tried them in my Z10 as well), in any event. They are probably not a good option for some of the table top dobs. And given these are cheaper scopes, this is the audience that might actually consider a chaeper eyepiece.
Hello Bogdan. I purchased 1 month ago a new Bresser 102/1000 mm here in Romania and it had a dirty lens. I sent it back and they gave me a second one. Curiously the second one also has a dirty interior lens but to a much smaller degree, just 3 relatively small dirt stains on the lower side of the interior lens. This one also has a few dust particles in between the lenses. Through the eyepiece everything looks great in my opinion. Now I don’t know what to do with it, should I keep it ? Should I send it back again ? Is it normal for refractors to have a more or less dirty lens when sold new ? I don’t know what to do with it. I would really appreciate you opinion. Thank you!
@3dfxvoodoocards6 Hi! Sorry to hear about your new telescope. Even though I don't believe that the dirt patches will impact the views significantly, I still think that you should send it back. It's a new telescope and you should get one in perfect condition for your money. The lenses of a new telescope should be in pristine condition. I wish you good luck! Let me know if you have any more questions.
Hello ! One question, how do you know when an eyepiece quality surpasses your main telescope quality and then you get no additional advantage on getting a more expensive eyepiece ? I'll give you an example, I have a Celestron TrailSeeker 80 Spotting scope and a 114 LCM and I attached an Omni Ploss Celestron EP and I liked the quality of the image , however, I wouldn't know at what point an EP would be overkill ? In Celestron lineup would the limit be Omni , Ultima, Luminous? I'm kinda confused and I'm just very new to all of this
@Gave-rf1hr Hi! The best way to find this out is to try out a new eyepiece and see how they perform in your telescope. As a rule of thumb, it's almost always a good Idea to upgrade the eyepieces telescopes come bundled with, but only after you had the chance to gain some experience observing with them. When you feel ready, look for a good mid-tier EP like the Luminous series. Another way would be to compare the price of the eyepiece with that of the telescope. If an eyepiece costs more than the whole telescope, chances are that the telescope will bottleneck that eyepiece. Hope this helps.
Technically any telescope gets advantage from better eyepiece: Because question isn't about what's the quality of part X or Y, but what's their product together to put it into mathematical terms. Everything you add into light's path will affect wavefront and image some amount changing it from the original. But obviously if telescope is garbage, even the best eyepiece won't correct that and you'll only see that bad image more accurately. So before getting expensive eyepieces, it's better to have decent telescope. Unless planning to upgrade telescope. And that 114 LCM is basically complete scam and rip-off from start to finish. You see Celestron hasn't been US company in long long time and is now just brand run from pretty much China. Optically it has blurry spherical mirror incapable to accurately focusing light and producing sharp magnification taking image, with equally cheap Barlow in focuser to further degrade image and make collimation far harder. And mount is flimsy shake gnerator even for that small tube. Basically anything below Schmidt-Cassegrains is hard to justify. And eyepieces aren't anything special either. While Omnis are good Plössls, that old design isn't up to date: View is narrow per magnification and at 15mm eye relief gets short and basically disappears in much shorter focal lengths making for bad ergonomics. Ultima Edges are Ultra Flat Fields (Altair/APM/StellaLyra/SkyRover...) with brand extra in price. Luminos is mixed bag with varying qualtiy and some of them available at better price as UWAs. (Astrotech/Auriga/SkyRover/Stellarvue/Tecnosky)
@@tuunaes thanks for your response , actually the LCM is gone now I sold it last week lmao Right now I only have the Spotting Scope Trailseeker 80, with the attached Omni of 32mm I get a very long eye relief which I'm now in love with . Gonna think about buying a real telescope later but the problem is here in my country pretty much the only brand you can find is Celestron . What about Svbony? Do you think is ok as a brand ?
@@Gave-rf1hr 32mm Plössl has the widest possible view in 1.25" eyepieces, so it's actually good eyepiece to keep. Svbony seems to have only refractors, so apertures are limited. Also fashionable short tube refractors are prone to high magnifications hindering chromatic aberration without more expensive construction.
Bogdan, your videos are always high quality and educational. Thank you. I have bought many items based on your recommendations and am very happy. For instance, I now have the full Morpheus collection and couldn’t be happier. Also I purchased the Baader T2 prism diagonal for my Skymax 102 and enjoy that. You are making a difference. Keep it up. Best wishes from Canada.
@simonthorp8565 Much appreciated! I'm glad my videos are of help to you. Clear skies!
Outstanding video, excellent for newcomers and veterans alike. I would mention an extremely long relief eyepiece for your viewers. This is the TeleVue 55 mm Plossl (price in the U.S. $256). At a 50 degree field of view it isn't in direct competition for wide angle eyepieces. But its quality is superb, its price is reasonable, and it is excellent for SAFE Solar viewing through the well-regarded DayStar Quark Hydrogen Alpha filter. This is because the DayStar contains a 4.3 internal Barlow lens. Your 600 mm refractor becomes a 2064 mm solar telescope. The 55 mm Plossl gives you a good view of the sun at a magnification of 37.5 times. This is a specialized use of the eyepiece, but when viewing the sun you don't have to worry about light pollution, and the sun is a dynamic object, constantly changing. These are just some thoughts.
@JamesAdams-ev6fc Thank you for your feedback! Even though the Plössl's optical design has some limitations like the narrow FOV, they can certainly deliver some excellent views of the night sky, especially the ones from Tele Vue. I hadn't considered them for solar observations, but I agree, they can be great for that application as well.

Hi Bogdan !!
Well TBH i ❤ the T2s so much i never tried the other variants. I am probably alone in feeling that the summit of the 20mm & 12mm optical Perfection was replicated in the T5 20mm discontinued now fl. I respect the ludicrous weight of it so when serendipity knocked with Pristine used examples i tried to not have super light and super heavy so made all of them somewhat heavy.

Thanks Bogdan! I worked hard to afford some Televue Plossls and a couple Delites. I'm not sure if Televue eyepieces are really worth the high price, but everyone swears by them. I agree that wide-field views aren't worth the cost of large, heavy and outrageously priced eyepieces. My Delites are fine, but I think it would have been better to get less expensive Plossls instead. I just want great optical performance. I"ve said this before, but for planetary viewing with my f/7.4 100mm refractor, nothing else beats the Takahashi TOE eyepiece. I'm not happy to recommend such an ultra-expensive eyepiece, but I think the TOE is worth buying if you want the best possible planetary detail in a 4-inch refractor. I was using a Televue 8mm Plossl with a 2x Barlow for the planets, but the Takahashi is noticeably better.
@vampolascott36 Thanks for your input. Tele Vue eyepieces sure are expensive, but they are very good and also represent a good investment since they hold on to their price for decades. I didn't had the chance to test the TOE yet, but I'll try to change that in the future and maybe make a video about it. Clear skies!
I have a Lunt zoom eyepiece that I've been extremely happy with for planetary and solar viewing.
@captainkoloth1631 Sounds interesting. I'll have to give it a try.
13:10 eyeglass wearers just be warned that the stated 22mm eye relief on the explore scientific 30 82 is not eyeglasses friendly because of how deeply recessed the lens is into the eyepiece. The effective eye relief is MUCH less. Still a beautiful and easy to clean (waterproof) eyepiece if you don't wear glasses.
Thank you Bogdan! I must say I like your style and the way you clearly explain the features, pros and cons of astronomy equipment to the benefit of others who can't afford to buy lots of stuff to try out. Your insights really help a lot! So thanks 😉
Great video Bogdan! You're educational guide helped me choose a good and budget friendly eyepiece. I recently got a Hyperion 24 mm and I'm very happy with the results. Thank you so much! 👍
Thank you again Bogdan, it’s great for a beginner like me to find an informative vlog on all the different eyepiece categories,
Brilliant
Thank you 👍
Enjoyable video. I have baader zoom 8-24 then bought baader Morpheus 6.5, 12.5 and 17.5. Now I barely use the zoom! I’d like a top quality low power one day and will probably complete my Morpheus collection. Just wish I was as rich as you! 😅
High quality/sharp "glass" is certainly addictive.
Getting 12.5mm Morpheus made 400 $/€ level APM (/SkyRover) 7.7-15.4mm zoom step above Baader Hyperion zoom feel totally mediocre.
You might want to keep eye on Baader prices in case they expand "annual" discounts from Hyperion to Morpheus:
After getting 12.5mm from "nearby" shop's relocating discount in last April Baader had (for the first time) 20% discount on Morpheus line in May and got others for €220. (including 24% VAT)
I like using a 100 degree eyepiece while viewing the planets because I can get most or all of the moons into the view as well. But that's just me. I use Ethos for medium (
The large and heavy ES eyepieces are great on refractors with heavy prime lenses up front where they look goofy slid well back into their rings when not laden with accessories near the visual back. With the heavier equipment mounted behind the mount's polar axis, you can slide the refractor well forward for a more esthetic look and more ergonomic eyepiece placement when the scope is aimed closer to the zenith.
Excellent video! A succinctly presented, categorized, cost/benefit analysis is exactly what is needed for making decisions with so many options. Thank you!
Excellent video. It would have also been interesting to see a category with cheap eyepieces :). Many amateurs like myself payed 200-500 euro for the telescop so 200-300 euro for an eyepieces will be too much.
@BurningFlame1999 I like the idea, thanks. Maybe I'll make a video about cheep eyepieces in the future.
Agree, similar for anyone got a deal on a used scope in same price range. Was lucky scored a dob 8 inch for half price and within driving distance pick up so no shipping cost too
Thank you for this video! Your expertise has grown a lot. I appreciate the large list of eyepieces for each category, and that the categories and brands are consistent. Finally I have the information I need to buy a wide-angle, long focal length eyepiece. It's gonna be an Omegon 32mm.
If you still like it after using the Televue, surely it's good enough for me.
Thanks for the great overview. This really makes me -again - think of replacing my Baader Hyperion with some Morpheus eyepieces.
Or maybe a Delos in the near future.
👍
@stefanfeichtenbock6949 Yeah, the Delos eyepieces are excellent, but also very expensive, especially here in Germany. For half their price you can get a Morpheus eyepiece which is capable of a similar optical performance. This is how I would choose anyway. Clear skies!
The Explore Scientific 12mm 92 deg, the 17mm 92 deg, and the 28mm 68 deg get very strong support when eyepieces in the premium range are discussed. Also, the Nagler T6 31 mm.
Another great video Bogdan! I'd love for you to review the APM Superzoom😊 Keep up the good work 👍
I have it.
It was second eyepiece after 28mm UWA "hand grenade" I got for my "small" upgrade from 110mm TAL-1. (250mm f/4.8 light bucket)
Then getting Baader Morpheus 12.5mm made it feel plain mediocre.
Sure it's possible that mine is below average "sample". But propability is for it being average and expecting it to compete against high quality eyepiece in any way being just too much.
Thank you. 👍🏻
I discovered the Masuyama brand (made in Japan) which makes lenses for many pro cameras (Nikon). Check this one out: MASUYAMA 1.25″ Series 85° (US$ 229) at AstroHutech).Focal length : 16mm
Apparent field of view : 85-degree
Eye relief : 10.0mm
Field stop : 23.5mm
Lens configuration : 5 elements in 3 groups
Coating : fully multi-coated
Physical length : 68mm
Outer diameter : 41.5mm
Weight : 138g
It's basically meant for f/10 and slower.
Five elements isn't even remotely enough to correct aberrations of such AFOV eyepiece well for use in fast telescopes.
Also 10mm eye relief is really short for the AFOV.
Awesome review and thank you so much I needed this review as I just got my first scope.
Very informative video....I do have the 2" Omegon 32mm ...purchased from your recommendation....its my goto ep to start the night.
I also have svbony 26mm and skyoptikst 15mm ,which both I like. I did purchase the 2-1.25 Omegon 7mm ..but also purchased recently Explore Scientific 2" 9mm...which I enjoy very much....keep up the great videos.
Another good video.
another nice video Bogdan. As I decided for the Svbony 107 ED I did flirted a bit with the Baader Zoom as a first eyepiece. Since I can get the SvBony Gold line 66degrees (6mm, 9mm, 15mm, 20mm) for 99EU I think I will get them and experiment with all before moving to more expensive stuff. I admit however if I spot a deal in EU or US for Morpheus 17.5mm I will jump on it, the big lens with wide field of view make it really attractive for glasses, hopefully it will be my main eyepiece offering 2.5 exit pupil.......but what am I saying here, first let's experiment with the gold line. I am however intrigued by the Hyperion which is on sale now in EU for 120EU , some say it needs to be opened and cleaned after one year (Morpheus is sealed even if is not actually water-resist like ExploreScientic)
@PauI__ Thank you! Never hared about Hyperions needing so much maintenance. I wouldn't worry about it. 120 Euros is a very good price for these eyepieces. They are totally worth it.
I'm surprised that nobody ever mentions the fine tuning rings for the Hyperion eyepieces in their videos. Personally, I think they are one of the strongest selling features of the series for people on a tighter budget. If you get a 13mm and 21mm Hyperion with the 14mm and 28mm tuning rings you essentially have 8 focal lengths ranging from 8 to 21 to play with for roughly $400 (9 if you remove the bottom lense off the 21mm and use it as a big 2" 32mm plossel). That's fantastic value in my opinion and you would be hard pressed to find a better deal.
Thank you for this very informative video! I'm learning new concepts everyday, because aside from the field of view angle, I have never considered its flatness as a factor. I'll certainly pay attention in the future. One quick question : There are no Celestron eyepieces in your list, and I'm not sure if I've ever seen one in some of your previous videos. Aren't they reliable and/or worthy ? The first eyepiece I bought after buying my telescope - the only one, so far - is a Celestron Luminos 7mm 82 degrees. I do like it but obviously, I don't have other brands to compare it to, yet.
@hellR1de Hi! I'm glad you enjoyed the video. I didn't include any Celestron eyepieces because the ones I tested so far weren't that convincing. But this is only my opinion and I didn't test all of them. For example I didn't had the chance to test the 7mm Luminos yet, so I don't know how good it is. The most important thing is that you like the eyepiece and enjoy the views through it. Clear skies!
@@BogdanDamian Totally right, thank you! I'm in fact, mostly curious about compairing them with a Tele Vue Delos or Nagler, with similar focal length. ;) To have an idea of how much a step up it is. I'm considering a Delos 4.5 or a Nagler 5, although it would push the limit with my Dobsonian 10" (254/1250), I guess...
Celestron doesn't really have anything remarkable for the price. (just like Meade... or SkyWatcher)
For example that Luminos line has inconsistent quality/performance. Though 7mm and 10mm are good, but those are blinged up versions of UWAs with usually significant brand extra in price.
Similarly Meade 5000 PWA serie is just brand overpriced Astrotech/SkyRover/Stellarvue/Tecnosky UWA made by Kunming United Optics.
@@hellR1de ~5mm eyepieces don't push anything in 10" Dobson itself. What they push is seeing.
Exit pupil (Eyepiece focal length / Telescope focal ratio) is good for measuring how much you're pushing telescope/aperture.
At highest have used 6.5mm Morpheus with 2x Barlow in my light bucket and that magnification is brutal for any issues in seeing.
Morpheus would be excellent step up from UWAs with both very high quality, wide AFOV (mostly actually 78°) and good eye relief.
Televue Nagler, which is actually "inspiration source" for UWAs, certainly has top quality, but as price of that small size has compromised eye relief.
Delos line again has long eye relief, but AFOV is step down and size and weight is big.
What would be a good eyepiece for smaller children (5-12)to view through? In my experience watching small children trying to view through a telescope they mostly don't understand the concept of eye relief and like to put eye right up to the eyepiece. Keeping that in mind while still picking an eyepiece with good clarity and fov to give the best possible experience for the occasional viewing that children might have through the eye piece. My setup is a William Optics triplet, 81mm aperture, 486 focal length, f/5.9. What would you pick for something like this and those other considerations for DPO and Planetary? If you had to pick a couple . Thx
@Jdub8025 For children I would prioritize viewing comfort, which is why I would recommend a Hyperion or Morpheus from Baader or a DeLite/Delos from Tele Vue.
Why haven't you recommend the APM/TS Optics HDC XWA models? They cost almost the same as the Morpheus line and the 100⁰ that they offer are a completely different and awesome experience.
I loved my Explore Scientific 14mm 82⁰ but when I tried the ES 14mm 100⁰ version, it just was on another ultra high category and replaced the 82⁰ immediately.
For 250-310€, the XWAs are just awesome.
Edit: if you haven't tried any of them, I recommend you to grab any of them!
Edit 2: my current eyepiece collection, after tried +40 ep, including panoptics, Nagler, etc is:
30mm ES82 for big DSO,
14mm ES100 for DSO and moon,
14mm ES100 + 2X Barlow for moon and planets.
I've recently also bought a 3-8mm Svbony as it was cheap for the 11/11 in AliExpress.
Also own 8mm and 12mm BST Starguider models, as I prefer the 60⁰ fov for the moon and they're really well corrected.
@Testeriosandandroid1 Hi Juan! You guessed it right. I haven't had the chance to test the HDC XWA yet, but I'm planning on trying them out soon. Thanks for your feedback! Nice eyepiece selection you have there. Which 2x Barlow do you use with your eyepieces? Clear skies!
indeed apm 100 looks really interesting. My only concern is the eyeplacement would be difficult, short ER, Morpheus looks like it has a huge lens diameter and should be really confortable to look trough even for kids, I must get something to ease the view of my 6year old kid
@@PauI__ Morpheus is about the widest AFOV eyepiece line with good eye relief/relatively easy to see view.
Already with 82° AFOV of UWAs and their typical eye relief you literally have to press eye close and start rotating head like peeking around the corner to see field edges.
100° AFOV would make it even harder and extra field would likely go completely unused by children.
And just seeing same field as in Morpheus would be harder because of shorter eye relief.
@@tuunaes morpheus is the one for my needs apparently, thanks
@Bogdan what ware your most used eyepieces, I know it depends on what are you looking at but I think is interesting for begginers in your case with mak102 newtonian and 4inch refractor what ware the eyepieces that got the most use over time
@PauI__ My most used eyepieces are the 9mm DeLite, the 24mm Panoptic and the 32mm SWAN. In terms of zoom eyepieces I use the SV215 3-8mm zoom a lot when I want to keep things as simple and light as possible.
I like your Fuji-yama T-shirt! from Paul @ Astrophotography Japan.
Hi Bogdan, thanks for another very informative video. I am very happy with Morpheus 6.5 mm for high power and Morpheus 14 mm for medium power observations! I get very sharp views thru both of them. I wonder if Morpheus lineup will have a low power EP in the future! At the moment, I am waiting for panoptic 27 mm for DSO observations! Panoptics (27 and 24) are difficult to get in the US, they are back-ordered everywhere :-(. If I can't get them in a couple of months, I will look into your other recommendations for low power EPs. Thank you!
Truly long focal length Morpheus would basically have to be different design and completely 2" size to fit needed field stop.
Anyway AltairAstro/APM/SkyRover/StellaLyra/Tecnosky 30mm Ultra Flat Field would good be complement and is called as honorary Morpheus by some. (also used as complement to Delos line)
28mm UWA (Astronomics/SkyRover/Stellarvue/Tecnosky) would be even little wider "hand grenade" but with mediocre eye relief.
Terve! I see. Thanks for that info. I will take a look at those recommendations!
@@mthirugnana I have that 28mm UWA under Tecnosky brand bought from their "Christmas" discount year ago. Fits Pleiades, Andromeda Galaxy+its satellites really nicely into view in ~1200mm focal length telescopes.
But seeing field edge needs pressing eye really close/"peeking around the corner".
Also it's big and quite heavy. This is early version with later ones having conical top and smaller eyecup : ua-cam.com/video/GFRCQYgzOD8/v-deo.html
Hi Bogdan, I have recently bought Celestron Starsense 10'' dobsonian f4.7. It came with some cheap 25mm plossl. I am trying to pick eyepieces to replace the EP that my telescope was supplied with and buy some additional ones to cover the spectrum. WIth logic buy once, cry once and be done with it I am aiming at Tele vue range. Panoptic 24 or 27 (both sold out with delivery around April) and Delite for shorter focal lenghts. I live in Europe and away from the big cities. I was thinking 2-3 EP + barlow or 3-4 ep without barlow. Which focal lenghs would you recommend? Thanks
@peter5204 Hi Peter, first of all congrats on the new telescope! I would recommend getting the following focal lengths: 7mm, 24mm, and 30-35mm. A 2x 1.25" Barlow would make a lot of sense in combination with the first two focal lengths. If the Panoptic eyepieces aren't available new, then look at the used market as well. It makes sense especially if you have the possibility to meet with the seller in person and check the EP out before buying it. That is how I got my 24mm Pano.
@@BogdanDamian Thank you, recently I am starting to think whether I should have chosen 8'' version as that one has f6 therefore less demanging on eyepieces... I live in Switzerland and secondary market here is relatively small. Also prices here are much lower than in germany, closer to USD prices. For example Baader Morpheus costs here around 260.- and TV Delite around 290 , Delos 390, pano 24 370. With such a small price difference between baader (morph) and TV (delite), TV is better choice, right?
@peter5204 I envy the pricing over there :) The choice between the Morpheus and Delite boils down to the AFOV and the accessories ecosystem. In terms of image quality they are almost on the same level. At these prices I would personaly go with the Delite.
@@BogdanDamian well from germany that is not so far for shopping trip :) wider afov would be probably nice thing to have but arent the ep with wider fov more prone to coma effect? I have read and see like million posts, articles and videos. I am literally going nuts here :)
@peter5204 While a wider AFOV will show more coma it is negligible in high power planetary observations. Chances are you won't notice anything at all. In this case you only have one relatively big object that you follow across the fov. If you think you would enjoy a larger AFOV, then get the Morpheus and never look back. It's an excellent eyepiece.
Thank you for a fantastic video it's helped alot... I noticed you have a skywatcher skymax 102 Mak, I just got the same telescope on a AZgti mount, do you have any tips for the focuser, one little touch will make it wobble like crazy.
@Slipperyducker Glad you liked the video. Also congrats on your new telescope! Its definitely a good one.
I assume you mean the telescope on the mount is wobbly and not the focuser knob itself, right? If yes, then responsible for the whole setup being wobbly is unfortunately the mount. The higher the center of gravity is the higher the instabillity. Try observing with you siting on a chair so that the mount doesn't need to be fully extended. Other than this and spreading the triod legs as much as possible, there isn't much you can do. The next step woud be to swithch to a more heavy duty tripod. The mount head should work in combination with any tripod on the makret. Hope this helps. Clear skies!
@@BogdanDamian Evening, sorry I should've gone into more detail 😅 the focuser knob isn't wobbly, what I find is as soon as you touch the knob to focus even ever so slightly it will move. But what you're saying explains alot the tripod that comes with the package is very lightweight, I will definitely try it at a lower setting. Clear skies.
Hyperion 24 sharp to the edge? Maybe at f10. The es68 24mm is much better in that regard. I replaced my 24 Hyperion with the earlier meade version 5k swa, and it was almost as good as the panoptic, and now i have the es68 version to replace it after my 24swa was stolen along wjth a bunch of other even more premium grade 1.25" that were in the same pelican style case with my televue pronto.
One thing you neglected to mention on the goldline (and also redline) eyepieces is that they are not great in fast scopes. Coma gets exaggerated very noticeably.
6mm and 9mm are well corrected for fast telescopes. (though 6mm has some issues in ghosting/eye psoitioning)
But 20mm and especially 15mm are oldies from time when f/8 was fast telescope and have lots of astigmatism showing on faster telescopes.
15mm one basically shouldn't be used in faster than f/10 or it will shit itself.
@@tuunaes I tried the 9mm redline in my 8" F4 newt, and ugh.. forget about it. Didn't try the 6 though.
@@twivel f/4 is pretty extreme with only few eyepieces designed for it. And without coma corrector already that would mess things.
@@tuunaes Actually, at F4, this scope isn't bad without a CC. I built it to travel and it's really compact, so I couldn't add the extra weight to it. The coma really isn't bad unless you use cheap eyepieces. When I tested the 9mm, the coma was 2-3 times worse than my APMs. Orion also makes a 25mm that isn't bad in this scope as well.
I would hesitate to buy these eyepieces faster than F5 (or maybe even at f5, as I tried them in my Z10 as well), in any event. They are probably not a good option for some of the table top dobs. And given these are cheaper scopes, this is the audience that might actually consider a chaeper eyepiece.
Hello Bogdan. I purchased 1 month ago a new Bresser 102/1000 mm here in Romania and it had a dirty lens. I sent it back and they gave me a second one. Curiously the second one also has a dirty interior lens but to a much smaller degree, just 3 relatively small dirt stains on the lower side of the interior lens. This one also has a few dust particles in between the lenses. Through the eyepiece everything looks great in my opinion. Now I don’t know what to do with it, should I keep it ? Should I send it back again ? Is it normal for refractors to have a more or less dirty lens when sold new ? I don’t know what to do with it. I would really appreciate you opinion. Thank you!
@3dfxvoodoocards6 Hi! Sorry to hear about your new telescope. Even though I don't believe that the dirt patches will impact the views significantly, I still think that you should send it back. It's a new telescope and you should get one in perfect condition for your money. The lenses of a new telescope should be in pristine condition. I wish you good luck! Let me know if you have any more questions.
@@BogdanDamian Thank you a lot for your replay :). I will contact the store and ask for a new one without defects :)
Hello ! One question, how do you know when an eyepiece quality surpasses your main telescope quality and then you get no additional advantage on getting a more expensive eyepiece ?
I'll give you an example, I have a Celestron TrailSeeker 80 Spotting scope and a 114 LCM and I attached an Omni Ploss Celestron EP and I liked the quality of the image , however, I wouldn't know at what point an EP would be overkill ? In Celestron lineup would the limit be Omni , Ultima, Luminous? I'm kinda confused and I'm just very new to all of this
@Gave-rf1hr Hi! The best way to find this out is to try out a new eyepiece and see how they perform in your telescope. As a rule of thumb, it's almost always a good Idea to upgrade the eyepieces telescopes come bundled with, but only after you had the chance to gain some experience observing with them.
When you feel ready, look for a good mid-tier EP like the Luminous series.
Another way would be to compare the price of the eyepiece with that of the telescope. If an eyepiece costs more than the whole telescope, chances are that the telescope will bottleneck that eyepiece.
Hope this helps.
@@BogdanDamian thank you a lot
Technically any telescope gets advantage from better eyepiece:
Because question isn't about what's the quality of part X or Y, but what's their product together to put it into mathematical terms.
Everything you add into light's path will affect wavefront and image some amount changing it from the original.
But obviously if telescope is garbage, even the best eyepiece won't correct that and you'll only see that bad image more accurately.
So before getting expensive eyepieces, it's better to have decent telescope. Unless planning to upgrade telescope.
And that 114 LCM is basically complete scam and rip-off from start to finish.
You see Celestron hasn't been US company in long long time and is now just brand run from pretty much China.
Optically it has blurry spherical mirror incapable to accurately focusing light and producing sharp magnification taking image, with equally cheap Barlow in focuser to further degrade image and make collimation far harder.
And mount is flimsy shake gnerator even for that small tube.
Basically anything below Schmidt-Cassegrains is hard to justify.
And eyepieces aren't anything special either.
While Omnis are good Plössls, that old design isn't up to date:
View is narrow per magnification and at 15mm eye relief gets short and basically disappears in much shorter focal lengths making for bad ergonomics.
Ultima Edges are Ultra Flat Fields (Altair/APM/StellaLyra/SkyRover...) with brand extra in price.
Luminos is mixed bag with varying qualtiy and some of them available at better price as UWAs. (Astrotech/Auriga/SkyRover/Stellarvue/Tecnosky)
@@tuunaes thanks for your response , actually the LCM is gone now I sold it last week lmao Right now I only have the Spotting Scope Trailseeker 80, with the attached Omni of 32mm I get a very long eye relief which I'm now in love with . Gonna think about buying a real telescope later but the problem is here in my country pretty much the only brand you can find is Celestron .
What about Svbony? Do you think is ok as a brand ?
@@Gave-rf1hr 32mm Plössl has the widest possible view in 1.25" eyepieces, so it's actually good eyepiece to keep.
Svbony seems to have only refractors, so apertures are limited.
Also fashionable short tube refractors are prone to high magnifications hindering chromatic aberration without more expensive construction.
Thanks for the video, brother. Intro music is a little loud.
No Pentax XW ?¿
@palmereldrich Haven't tried one out yet, but I'm going to change that soon 😉
Nice. I never actually use eyepieces. I use a camera.
Your username misspells "amateur."
@@scoutisabelleProof of my amateur status.
You really need to try eyepieces, photos are nice, but nothing can touch the beautiful views through the eyepiece...
Good info but the 1 second flash of the photo and specs is very irritating. Keep the eyepieces and info on the screen, not yourself, please.
