Awesome time-lapse man. The sun is pushing more storms our way so plenty of other changes to get a few more. Take care
Thanks much. Hopefully more to come !
Wow
A beauty of a storm!
I have one of this... and it's my frienemy scope... The lens cell is a catastrophe with its sideways screws which align the focal axes of the two lenses. If you knock the tube against something the two lenses get misaligned and it's a pain to get them aligned once again. The push-pull screws that move the doublet as a whole are ok, but no matter how well you collimate the scope with a collimating eyepiece, if the two lenses are misaligned to each other then you have to tackle with the 6 sideways screws and risk to chip trhe sides of the lenses... I took out those screws and tried to fill the gap between the lens and and its mount (it's about 0.7-1 mm!) with pieces of thin aluminium sheets. Now the two lenses are held firmly to each other and though the collimation is still not perfect, it's ok. The lens itself throws up a huge amount of false color, the image is washed in a noticeable purple haze, but that's not the most annoying part... It also has a fair amount of spherical aberration too. At 200x+ magnification the spherical aberration starts to annoy you and the planetary images are not so sharp as you might expect. However, when you stop down the lens to 100 mm (5") it will show acceoptable planetary images at 200x. With the lens stopped down to 100 mm I split delta Cygni, which is quite good. As for the Moon and Venus: I dunno how these Moon&Venus photos were taken but this scope will show a huge amount of purple haze around the Moon & Venus... I think those photos were taken with green monochromatic filter. What i like in this scope? 1. The focuser. 2. It's a great visual DSO scope! I use it within the 30x-120x range with a "dobsonian"-like mount made by myself and it is a pleasure to use it this way. No need for adjustment screws, just slew in the right direction and look at what you want. It's well balanced and i move it with just 2 fingers... And when changing eyepieces it stays firmly in place, it does not wobble when you try to reach focus. 3. It has a fair amount of field of view with some good eyepieces. Would I buy it once again? Nope. For imaging a fast 8" newtonian with coma corrector is a far better choice. For visual I'd rather buy the 152/1200 skywatcher achromat.
Suppose it depends on your intent. I bought this for solar imaging and it is great for the purpose when considering the price point. The whole purpose in this video is demonstrating that it has a lot of additional flexibility when used correctly for the purposes. It is absolutely necessary to use filters and or techniques to sidestep the issues at the extremes of the spectrum. Is it better to purpose-buy a scope for each purpose…100%. But at what cost?
That’s insanely cool
Thanks. 🙏

How did you prevent the core from blowing out? Is this a composite?
HDR blend of two sets of exposures.
How did you do that because jupiter rotates very fast and also how did you combine the 4 videos?
I keep the individual videos short in duration so I can stack them and not see blur. Then I derotate them within WinJupos so that they align. Finally they can be compiled together into a color image.
Oh alr thx
yeah if he has a crazy fast camera theres no need for long exposure time
@@Spaceandthings1 planetary photography in general doesn't need long exposures ideally you want to be shooting video. this applies to most if not all cameras including phones
@@Techit59 yea I know what I meant is that since his camera has a high fps, he has time to shoot filters
Do u have any videos describing how you process images?
Not at the moment, but I do plan to push more videos out soon.
What telescope do you use?🔭
This was shot through a 12” f/4 newtonian with a Televue 5x Powermate and ASI183MM camera.
@@TheVastReachesthanks
Just 7.5nm FWHM is enough to get all the granule details and contrast? For Chromosphere, how about replacing the 7.5nm with an 3nm Ha filter?
The granules are a broadband feature, meaning they can be viewed with a wider bandpass. Unfortunately 3nm is not narrow enough to see narrowband Ha details... for that you need a filter bandwith less than an Angstrom. That said I also have a nagging curiosity about what you actually COULD see with this setup. I just dont have a 2" 3nm Ha filter. Considering the cost of that and the wedge, it may be better to just get an actual solar Ha filter, hahaha!
Great video, I just found a G1 Wedge while going thru my dads gear. I would like to use it on my SCT but I would be worried about heating up the internal optics.
These are not to be used with reflective optics due to the heating issues you mention.
This is beautiful

It was so very
How does this have so little views? Extremely talented.
🤷♂️. Thanks
I have an Isle of Man SolarScope SF-50 filter set that I have been using on my Takahashi Sky 90 ll. However, I just acquired a 4" f/15 Unitron clone refractor. The 4 inch f/15 needs an adapter, but I have something around here I can use... I'm just waiting for the sun to come back 😂 .... Love the images 😊
Thanks. Good luck! 🌞

Still works!
Yup it looks way better with s24 ultra
I’d hope so. This is an iPhone 6. 😂
@@TheVastReaches ya lol
Don't you find it weird that the solar eclipse in 2017 and the solar eclipse in 2024 were exactly the same amount of days away from when the us HAD to get vaccinated for COVID-19. Yep that's right. August 21 was 1211 days away from December 14, 2020. April 8 was 1211 days away from December 14, 2020. Isn't that kind of weird that we could've predicted COVID-19.
I have thought about getting a large achromat for imaging, but I use an OSC camera with my 5 inch newt usually and I just don't think I could part with the apochromatic nature of it. I do plan to do some experimenting with some of the smaller achromats I have just for the fun of it though. However, I would LOVE to see what some DSOs look like though a large refractor like that visually.
I don’t have the skies for visual. I’ve also used this scope with OSC and I’d pass on that unless you filter the incoming light. It does great in narrowband but even multi-band narrowband would present challenges with focus position being off for some of the bands.
@@TheVastReaches that is about what I figured unless you stop the scope down and use a fringe killer filter and even then you would be better off with day an Svbony 102ED. I live in a bortle 3/4 area though so I think it would be great visually for me but I have no need of one since I have an 8" dob. I would just like to try one
I did on my phone android. Used an eclipse lense Pro mode I put my phone ISO at 50, and shutter speed at 1/12000 got amazing photos. But for totality, I made the speed around 1/6000
Cheers. Glad it worked!!
DO NOT ZOOM IN!!!!
Why not?
Considering most phones will switch to a longer focal length lens when you do, it’s a good idea to to zoom in.
Thanks man😢😢😢 I never seen a eclipse my whole life and im new to this and i have a iphone 11 and dont have any ISO approved glasses
Sorry I got this late. Hope you could make something work
@@TheVastReaches i did actually! I borrowed glasses from a library and stared at the eclipse although it wasn’t a totality
@@Mayaisbeautifuli was there to, i got glasses from a library . what library did you go to,
@UCWJJo_JrKf7rFmSfW391oGw NY Library!
@@Mayaisbeautiful Quick internet tip Don't send out personal locations online
so if its over your phone and your looking at your phone do you still need them on yours eyes?
I ordered 2. I’ll put one on my face and the other on my old phone (won’t risk my new phone) and yeah.. never view the solar eclipse without proper ISO approved glasses
@@daisies4thestarsyou won't be able to see your phone if you put the glasses
@@nishanthmohan well the trick is just to do it in a good timing or ask for assistance
Plus public viewing are ideal as many photographers gather there and you can ask them to send you a copy u won’t have to risk anything or buy any fancy equipment just find the right person who might share the photographs with you
I actually just ended up putting them over my Nikon camera lens and looked at the 3in screen from a distance an watched/rec it. We git 97% an was cool looked like a boomerang with fire tips. My iphone sucks at pics an videos. Thx peps
Thank you man
One of the better astronomy equipment reviews I have seen, keep it up!
Appreciate that, thanks!!
Wow.
Exceptional video - purchased the wedge based on your review and now planning some pics prior to and after totality; have two other setups for totality and to do a composition…
Good to hear! Thank you. Best of luck on the weather.
Wonderful video and explanation. I just purchased an ES AR102 "open box" but haven't used it yet. I'm curios about focuser upgrades for these scopes in general. In my initial assessment I find that the stock focuser has some slip/jerk to it even after loosening the lock and tension screws as well as loosening and realigning the hex head screws on the drawtube. Any insight/experience with this would be greatly appreciated. I have a message off to both Highpoint Scientific and Moonlite focusers for a fix or replacement, respectively. Thanks!
I updated mine to a Moonlite. Honestly, the stock focuser was ok, but I did experience some tilt when I was solar imaging. The equipment was hanging far rearward and it just wasn’t the best option. I did image for years with the stock focuser though and it performed admirably for what it was ! Good luck. I can answer any questions you may have about the swap. Ron at moonlite would tell you exactly what you need and honestly it is a great upgrade.
Excellent video. Appreciate your honesty as well as your clear description of the product
Glad to hear that. Thanks!
Wow! I've done them separate but never got as much detail!
Thanks … it’s a fun spot to image if you have a super wide-field like this.
Is there anything that can get that detail that isn't that $1,300 Quark?
Unfortunately that’s near the price of entry to see the chromosphere. A solar scope like a Coronado PST or Lunt 40mm could provide some views like this but small aperture scopes like those would deliver less detail.
@@TheVastReaches Sounds about right. thanks for the quick response. I am new to astrophotography. I picked up a AR127 and am trying to get it eclipse ready. Any suggestions on that? It's on a Celestron AVX. Sorry for all the questions great videos though! Definitely subscribed!
I love the daystar quark, just wish it didn’t cost to much…
It is pricy like any ha solar filter is, unfortunately they aren’t easy to make well
I'm glad to see someone on UA-cam doing serious astrophotography with an ES AR refractor! I bought an AR102 for what I think is a bargain price and tremendous value. It came with everything necessary for visual astronomy except a mount (which I also bought) and eye pieces (which I already had). I intend to get a mono astro-camera for the same reasons you mentioned. The quality of the images you shared in this video make me feel like I made a good choice. Thanks!
Right on. There are the drawbacks but they are certainly a great value in the right hands.
It either be a satellite or a ufo
Or a witch.
Great video!! you need and deserve more subscribers. I noticed the UP shirt, my best friend lives in Munising! Thanks for the info.
Thanks! I haven’t made a ton of videos so I’ll chalk it up to that. Cheers to the mitten and its northern arm is the best !
I loved your video thank you. I read somewhere that a Petzvel design astrograph cannot use wedges like this because of back focus issues. Do you know if this is true? Any way to get around this limitation? Thanks again!
More importantly, Petzvels should not be used for any solar observation application. The sole exception to this is a front (objective) mounted energy rejection filter. You must be sure the concentrated beam at the back of the telescope encounters only filters designed for safe solar observation. A petzval’s rear elements are not designed for this and could create a safety hazard. By all means, do your own research here but I would be very careful with an application like that. Otherwise, any telescope that can focus with a diagonal should be able to focus using a Herschel wedge, as the focus plane will be the same. And thanks! Glad you found the video useful.
Thanks for the information. I’ll just use a Baader film for now!@@TheVastReaches
So does the photographic version contain everything that the visual version does … that is, if I purchase the photographic version can I throw on an eyepiece and observe visually? Also, can I use it on my Orion Eon 130mm triplet without any extra filters out front? Great video, by the way
Yes and thanks! The photo version just comes with extras, those being additional ND filter options. It is safe to observe visually through using the setup explained in the manual which is the “Visual” version configuration and that is all supplied in the “Photo” version and the way it is configured upon delivery.

Achromats are truly underdogs. They can also produce excellent images. Btw sir can you tell how you are getting natural colours of stars. Like blue colour of blue stars, orange color of orange stars. Plss
Generally, my deep sky shots though this scope are narrowband, so they are either a natural HOO palette mix or perhaps SHO with some tricks of removing the green component and color shifting them (though there is variation in the colors, I’m not sure if it’s “natural” at that point).
@@TheVastReaches ok
That was a satellite you mong
Wow it's my mother in law where is going 😮
Haha
For solar photography, do you use a aperture or solar energy rejection filter, or stop, when using the Daystar Quarks or do you just add a UV filter before the ZW174 mono camera? Love your image captures!!
I use 2” UV/IR cut before the quark for this setup… I place this as far forward as possible within the drawtube. This needs to be in front of the quark to prevent damage. Thanks for the compliments.
