Thanks for your support! - Наука та технологія
I have recently bought an Omegon 38mm 2”swan eyepiece and UHC filter and in combination with skywatcher 200/1000 reflector, it works perfectly. Thank you for your tips about improving DSO observations!
Thanks for this highly informative session
Very informative video. Thanks for sharing.
Bester Teleskop-Kanal, den ich kenne 👍👍👍👍😁
As usual Bogdan, very professional video.
Thank you for your efforts.
I moved to Oregon recently, selling my 10" Dobsonian before leaving.
We are finally settled again, and I will be trying to decide whether to get a 12" Dobsonian or an 8" Schmidt Cassegrain.
Not sure yet.
We are in a bortle 3 sky now.
Enjoying just how many stars are really out there.
I want to see a bortle 1 this year.
@Rick Knight Thanks, glad you enjoyed it. Regarding the telescope upgrade I believe that there won't be a big difference between a 10" and 12" dob. An 8" sc would be more versatile albeit with a smaller aperture. I'm currently also thinking about switching from my 12" dob to a 7" Mak or 8" SC with goto and an equatorial mount. They would be much easier to transport.
Seeing bortle 1 skies would be amazing. I would like that very much as well.
@@BogdanDamian I live very close to Bortle 2 (30 miles) and Bortle 1 isn't much further, but it is hard to tell the difference. I find my nearby Bortle 4-3 is easier to find things as 1 to 2 Bortle can be overwhelming if the DSOs you're looking for are in front of the Milky Way and its Halo. It is just, "Oh Wow! Where is Sagittarius' Teapot start and end?"😆
Try, I had my mirrors refigured to near perfection and aluminized to 97%. It is a C6-N Newtonian and having near perfect mirrors is a big big difference, "better than my 8" according to several guys in my Astro club. Warning! You must have decent mediocre mirrors to do this to start. My mirror only had a small anomaly and they only charged me $128 to start, but it can cost more than double that.
@Mountain Fisher This sounds really amazing! Regarding the mirrors, mine are in too good of a condition right now (only 1.5 years old) but when the time comes I am going to refigure them as well. Clear skies!
The reality is recreational sky watching by necessity is going to be around your house. Whatever the sky gives you is what you have to look at. Therefore for viewing, I use two scopes: 1) A 102mm AZ refractor for moon, plants, double stars and bright clusters. 2) For big sky objects a 10" 1250mm Dob with 36mm to 10mm lenses does the job when it is dark. To find faint objects in brighter skies the StarSense smarphone App enabled system is excellent to get the most out of your time viewing.
Ah yes, my favorite night sky object, plants.
@@maxil8988I too study plants at night with my 8" telescope
nice video
I like very much the baader zoom 8-24
Hi bogdan for me the most important thing for deep sky is going somewhere very dark, there isn't much point having a big scope if u need to filter out light pollution, may as well have something smaller u can manage and get ur self out in the sticks, it's a amazing what u can see even in a 100mm under a good sky and a good eyepiece, I'd also recommend anyone looking to get anything over 130/150mm to go to a shop and actually try moving it around, taking it apart so on, think where ur going to keep it and how your getting it outside, are there steps/many doors to get thorough, or u may just have an ornament in the corner if u can't manage it on or own in the dark 🤷♂️( a simple mistake I made 😅)unfortunately we all get court up the bigger is better, but visual astronomy and the astrophotography photos you see r very different a lot of deep sky objects just look like a smudge even in my 10 🤷♂️ 👍but looking amazing in a picture taken by an 80mm after hours of exposure and 1000s of images stacked 😀 👍
@Andrew Pattie I totally agree with what you have written 👍
An alternative to flocking, and easier to apply would be painting the inside of the tube with Black 3.0 or Musou Black paint.
Anything bigger than a 10" Dob look for truss style. Solid tube will be too bulky and heavy to manage by one person. Best aperture to size/weight ratio is the Obsession UC15" compact dob. Cost and wait time is another issue.
Truss tube dob. Big, light, portable. But, not cheap.
I own a 8 dobsonian goto I use everytime and a 16 with push to I use once time a year to meeting
So I don’t know use it very well and my favorite is the 8 goto
hello, excellent videos! One question, what are your 3 ocular you use the most for deep sky observations?
@Raul Munoz Hi and thank you! For deep sky observations I use the 24mm Panoptic from Tele Vue and the 32mm SWAN from Omegon. I currently don't feel the need to have a 3rd one.
I have an AZ-EQ6. I want a good visual scope for DSOs. It seems like a reflector would be best for that. Skywatcher has said 10” Newtonian is the limit for visual use, and 8” Newtonian is recommended to for astrophotography. I live in a bortle 4 area and my backyard is wide open with no trees so I can see most of the sky on clear nights. I was thinking the Skywatcher Quattro 250p, but I was wondering if there’s any better options in your opinion. Thanks!
jonathanpineda2774 The 10" quattro is definitely good for astrophotography, but if taking pictures is your main goal, then I would recommend a good doublet refractor instead. Something like the evostar 100ed from Skywatcher.
Hello Bogdan, I have a 12" Orion Skyline dob. I'm thinking about purchasing a Tele Vue Ethos 21mm with a Tele Vue big barlow to replace the eyepieces that were included with the scope. Any opinion on this combo? I'm in Bortle 1 skies by the way.
@namewitheld I believe the 21mm Ethos will be an excellent fit for your 12" dob. The 2x Big Barlow should also work well together with the Ethos. It's parfocal and it will also increase the eye relief a bit, which is a good thing. There is a slim chance that you won't be able to reach focus when using the Barlow together with the Ethos, but I don't believe that this will be the case with the standard focuser on your telescope. But if this ends up being a problem anyway, then a solution would be to go for a 2x Powermate instead of the 2x Big Barlow.
@@BogdanDamian Thanks very much. It's a major purchase and I'm glad to have your opinion. Love the company content as usual.
From the light pollution map you shown it looks like the place to be is Austria and the place not to be is Belgium.
@Iornaz1975 In general în Europe the more mountainous the landscape the fewer the towns and cities are. The south part of Germany where the Alps begin also offers some nice places with low light pollution.
Hi, I m a beginner on stargazing and I had an difficulty to find the star etc as it is too small with my reflector telescope.. What shall I do?
@yapgideon I suggest you download an app like stellarium to have a better overview of what your telescope roughly is pointing at. At first try locating a very bright sky with the finderscope, center it and then using a long focal length eyepiece (>25mm), try and see if you can find that star. If not you need to align the finderscope with the telescope. Once this is done the object you are looking for should appear in the eyepiece's field of view as well. If you have a more specific question, just let me know. Clear skies!
Hi Bogdan, first of all thanks for all these wonderful videos. In my case, as beginner, I purchased a Skywatcher 150p Heritage, that I use with an alt-azimuth mount. I've purchased the 4.7mm 82deg/11mm 82 deg/24mm 68deg Explore Scientific eyepieces (following your advice) to maximize the optical quality (without breaking my wallet) and a good nebula filter. I've prioritized total portability and easy of use (I can set up in few minutes and take everywhere), also because I don't live in a deep sky area (the closest ones are 50km from me). Do you think that when I'll be more advanced this set-up will look a bit limited to me, or is something that I can keep in the next years for both deep-sky and planetary?
@Enrico Pascucci Hi! I'm glad that you find my videos helpful. Your Explore Scientific collection looks very good so far. These eyepieces are excellent and will definitely offer you amazing views for many years. I don't think they will limit you in any way as they can hold their own against premium eyepieces like Tele Vue and Pentax both for planetary and deep sky observations. The telescope is good as well. Maybe if you are to get into deep sky more seriously down the road you could think about upgrading it to something with a larger aperture, but don't think about that right now. Just enjoy the night sky with your nice setup 🙂
Thanks, Bogdan. I had created the setup watching videos and taking info in Internet but, being new to astronomy, I feared I had gone through some wrong choices. Now you confirm they were right decisions for me. Effectively the first views I've had (the details of the moon, M42..) were really rewarding.
Wise choice! You've spent the money you saved by choosing a smaller telescope on some really decent eyepieces which is absulutely necessary at f/5. Keep in mind: the tabletop design demands a really stable chair or table for best experience (check topics on DIY tripods made for this purpose on forums like cloudynights or stargazerslounge). And there are two very cheap and simple, but really important DIY mods: one for stabilizing the focuser and a light shroud because of the truss-tube design. There are several videos on UA-cam on this topic so check them. Experienced people on forums say, that aperture will give one at least a decade of observing.
I meant DIY collapsable tripod chairs, not tripod mounts, sorry.
@@user-hn1gw1gt7d thanks for the feedback and the advice.
Does the diameter of the eyepiece matter much (e.x. 1.25" vs 2")?
@Jonathan Avesar The barrel size, isn't really directly responsible for the image quality of an eyepiece. It's more of a consequence of how wide the field stop of the eyepiece needs to be. For example if an eyepiece has a long focal length and a wide AFOV, then the diameter needs to be big and such an eyepiece will come with a 2" barrel size. A 24mm eyepiece with a 68° AFOV can still have a barrel size of 1.25" and still utilize the full beam of light coming out of the telescope. That same eyepiece with an 82° AFOV will need a 2" barrel size in order to utilize all of the light delivery by the telescope. Hope this helps.
@@BogdanDamian yes, I understand! This video was super helpful, thank you!!
I was thinking of stepping up to a 12” dob over my 8” dob. Would the details in the 12” be worth the cash and weight, or should I stick to the 8”? I live in a Bortle 6 area
@fredaw61 It depends a bit on what you like to observe. A larger aperture will improve the views of fainter point sources of light like stars no matter the light pollution. It will simply be able to show you more stars. Extended objects such as DSOs will not benefit as much from a larger aperture. The best way by far to improve DSO observations is to take the telescope to a darker sky area. An 8" dob will show more details under Bortle 3-4 than a 12" under Bortle 6.
@@BogdanDamian I like observing bright Nebula and Galaxies the most. Next would be planets. What then would be best suited for my home viewing. I don’t see me going to darker skies and hour and a half to two hours away. I also have been looking at a 6” SC with a 1500mm focal length for mostly planets and the moon.
@fredaw61 In this case I would probably stick to the 8" dob. I know that this probably isn't the answer you are looking for, but for Bortle 6 you really get diminishing returns from going with a larger 12" aperture. Sure it will improve the views a bit, but I believe it will only be like 20%-30% and not 100% better what the price might suggest. And on top comes the increased difficulty of storing and moving a 12" dob. I own one and every time is a bit of a struggle to get it set up outside. In my opinion a 6" SC won't necessarily offer better views compared to the 8" dob. It's still a reflector with a smaller aperture. An SC would make sense if you are considering astrophotography as well.
The only option in terms of telescopes that might be worth it, is a good 5" or 6" refractor, like the 120/1000 or 150/1200 EvoStar from Skywatcher. It will definitely improve your views of the planets/moon while DSOs won't necessarily loose detail compared to the 8" dob.
Alternatively you could invest in better eyepieces or accessories like filters. This can also help when observing under light polluted skies.
@@BogdanDamian I know it won’t help pull in the faint objects because of the light pollution. What I was hoping for was just some more detail and maybe a little color in what I can already see. I do plan on getting some light pollution filter like an O lll I believe and maybe a variable polarization filter. I kind of remember seeing more detail out of my 10” SkyQuest years ago. That was my other option.
@@BogdanDamian okay, I have come to a compromise, or conclusion. I think what I will do is step up to a Celestron StarSense 10” and forget about the other two. If I bought the 12” I would need a cart and have to store it in the garage. Something I am not comfortable with because of the car exhaust and extreme temperatures in the summer. Also I would need to have a StarSense mount made for it. Sorry, but I love the StarSense. I will skip the SC like you said. I am not doing astrophotography. The 10” will give me a little more detail and not pulling in as much light pollution like the 12”. And if I can get to a dark sky sight I won’t be disappointed that I only had the 8”. I may sell the 80mm refractor, but still hang onto the 8”, or even let that go. The plus also is I could manage moving the 10” with out much more difficulty. One wrong move with the 12” and I fear my back would go out. I do have a dislocated vertebrae at L4-L5.
ola, quero comprar um dobson 10 polegadas , qual é melhor ? omegon , GSO, skywhatcher ? obigado
@Carlos Nascimento Olá, as três marcas oferecem o mesmo nível de qualidade. As diferenças estão nos acessórios que são entregues com os telescópios. Portanto, escolha um que esteja disponível na sua região e talvez consiga obter um desconto.
Tenha em mente que a Omegon e a GSO utilizam a mesma óptica que ambas são fabricadas na mesma fábrica.
Cada uma das três empresas oferece versões especiais dos seus telescópios Dobsonian. Posso recomendar a série ProDob da Omegon ou a série Deluxe da GSO. Ambas têm muitos acessórios incluídos.
Espero que a minha tradução seja suficientemente boa.
@@BogdanDamian muito obrigado . otima tradução
@@BogdanDamian mais uma vez obrigado. já fiz a encomenda do ProDob da Omegon pela astroshop.
@Carlos Nascimento Isso é óptimo! Digam-me como gostam.
Olá , já fiz a encomenda, chega na terça feira o Omegon Telescópio Dobson ProDob N 254/1250 DOB II.
The largest reflector you can handle and afford with a Zambuto mirror.
That will even do great on planetary detail.
Just not good for photography.
76mm aperture can see deep sky object??
You can see Andromeda Galaxy and Orion Nebula with naked eye...
You just won't see much details or size with low light gathering power of eye and low magnification.
And 76mm isn't that great either. Its light gathering ability is basically at level of 7x50 binoculars.
Bogdan ! Hellllp meeee. I live in the U.S. I want to spend a max of 3000 with the intention of spending more in the future. I want to build an EAA/visual rig using a reflector and platform or mount. I have only a laptop. I have been trying to do it myself with the internet and have given myself 100 migraines. I live in the flint hills of Kansas. My skies are peoples dream skies. I don't need the best of anything but won't settle for the worst of anything. Plz help. :(
@kevingumfory Hi Kevin! Putting an EAA rig together isn't necessarily straight forward. There are a few key aspects to keep in mind, but since you like reflectors, I would recommend the 8" reflector on the 200/1000 PDS Explorer on the EQ5 Pro mount from Skywatcher. It would be a very good start, especially if you want to focus more on imaging. Alternatively, if you want a bigger telescope like a dob, then the go to enabled flextube series also from Skywatcher would be a good option as well. If you can't get your hands on Skywatcher dobs then check out the go-to skyquest xt series from Orion.
As for the camera, look at the ZWO ASI 183 MC Pro Color for example. It works very well with Sharpcap which you can install on your laptop. I would also recommend to get a rechargeable external power supply to be able to power everything up. Hope this helps.
