Most interesting. I'm thankful you mentioned that BlurXterminator could deal with the chromatic aberration you found with the 0.6 reducer, perhaps show before and after its use, if you find something similar in your next product review. It will also help us new folks when you explain the ramifications of pinched optics, or other findings you mention in multiple instances during a video.

Thank you for your feedback, that's very helpful and much appreciated. I went ahead and made a comparison video to show what the .6x Reducer + 103 APO's chromatic aberration and elongated stars looks like before and after using BlurXTerminator in the video linked below. Video: drive.google.com/drive/u/1/folders/1y0GBSYrOjrRn9HkqsZwoRwmUt8Wn4YJF (if it's blurry, it just may need a few moments to buffer) The first image is of the single, 45 second exposure (raw, only debayered), and the second image is of 5 stacked 45 second exposures (debayered + image integration) to see how the chromatic aberration becomes more apparent in a stacked image/ more light collection and then to see how BlurXTerminator version AI 4 corrects for that along with the elongated stars. For the pinched optics/ issue with the larger star and triangle-like diffraction spike, the more integration time, the more apparent it will be in your final stacked image from my experience. Particularly when there are a lot of large, bright stars in the frame and when you're using a scope with a long focal length/ are very zoomed in. I hope this helps, and thanks again for your input!

The .6 reducers corner elongated stars might be a back focus issue that can either be solved with an Askar back focus adjuster or adding shims. At post BlurX AI 4 might fix it as well.

22:27 That weird shapeness in the stars usually is due to the notches in the locking rings of filters and lens shown at 16:14 and 17:21 . Best practice is to keep the filter as close as possible to the sensor and to avoid flattners/reducers with those internal lock rings notches exposed to the front objective which skews the light path. Overall great scope with nice round stars.

I'm pretty sure the gap/spikes on Mirfak are from the flattener. Look inside the flattener, you will probably see a small gap in the metal ring that holds the elements in. All my flatteners/reducers have this gap and cause similar gap/spikes. Each flattener/reducer have unique spikes. A way to test for pinched optics is to put as many dew heaters as you have on the ota, warm it up super good will imaging and see if the spikes go away or change. Good vid, keep it up and Cheers 👍👍

Thank you for the review! I've used a lot of APO refractors and pinched optics is usually easy to fix by unscrewing the shipping screws in the lens block. Most of APO refractors come with 2x sets of screws, one set for calibration and the other set for shipping scope to keep the optical elements in place. Anyway, do you think this scope would be a good upgrade from the 94EDPH?

Thank you for your input on this! I'm still not sure what exactly this is. I think it may have been some sort of internal shavings in the way or something. Looking more into now that I'm back from eclipse travels. Regarding your question, I don't have direct experience with the 94EDPH, but have heard nice things about it. I think if you're looking for a bit more reach and resolution, with some flexibility in terms of focal length/ ratios with the optional accessories, this would be a good option. It's fairly lightweight still, too.

Sarah, This is probably the most unusual question asked of you so far. Here goes......... I own a Fuji GFX 100s Medium Format camera and was looking for some sort of refractor to use as a "long lens". The sensor is 33mm x 44mm (so I guess if you use the old A squared + B squared = C squared formula the diagonal / image circle will be 55mm). I've found a company that makes a T-Adapter for my camera to the scope, but I'm just wondering how on earth this thing might work for daylight photography, and how I might generate an image circle big enough. Quite a doozy, I know. Any suggestions would be helpful. Larry

@SarahMathsAstro

Larry, I'd imagine that this would do pretty well for daylight photography (not solar of course since you'd need lots more gear for that). But yeah, with the 55mm threads on the back of the flattener, .8x reducer, and .6x reducer, you may be able to get your camera attached.

Very thorough review. But I don't think that is pinched optics you are seeing around Mirfak. I bet it's lens cell clips protruding into the field. If you still have the scope, can you push the lens shade all the way in and examine the lens cell closely with a flashlight. Check if you can see three clips evenly spaced around holding the lens in place.

I wouldn't necessarily say it's closed off (in terms of the glass internally not being exposed when detaching the backend). That is something to consider, no doubt. I think if you're not changing it out constantly, that certainly helps. I felt like I got more dust with the Askar V and changing everything out while testing because I was going through/ swapping so many different pieces of glass (the two objectives/ the different optical accessories), taking them on and off, etc. But with the 103 and the back end, I didn't have much of an issue with dust, or at least it didn't appear to be an issue. If anything, I would tilt the tube down and use a blower and let the dust fall out if there appeared to be any. Great questions and valid concern. Thanks!

@SarahMathsAstro

Hey there! You could go with either or. I know many visual astronomers who love their schmidt cassegrains (SCTs - I never get the spelling right with this one, lol), Dobsonians, and refractors. I think if you're looking for something with a lot of visual prowess in terms of resolution and light collection, and don't mind having to collimate mirrors and have a place to store it, then Dobsonians/ Newtonians are pretty phenomenal for visual as are SCTs. Refractors are too, don't get me wrong. They're incredible. They're just very expensive for the same amount of focal length, etc. Refractors are great though for their optical quality and the fact that they require less upkeep to use them, in terms of not needing constant collimation (if ever after the first time from the factory), like Dobsonians/ Newtonian, and SCTs do. I don't know if that helped at all, but hopefully.

@@SarahMathsAstro Thanks so much for your input Sarah. I really appreciate it. I think back to the days I had that old Meade refractor and I couldn't see barely any color in Saturn or Jupiter looking with the naked eye. Watched a video late last night where someone did comparison between $1K and $10K refractor and the difference was unreal. Am I correct in assuming with mono camera you can get higher resolution and the filters make it so you basically sample singe frequency (or group of frequencies) to build a kind of artificial color image by giving each sample the equivalent of (RGB)? Although I think you call it something else by what you were saying in one of your other videos, and what little I've read up on it. And that you can get more detail with mono vs full color camera? (but I'm assuming you need to take more pictures to assemble final image). Sorry for all the questions. If I ask more I should probably send you some $ for your time....LOL. BTW, I was recently drooling at a 14" SCT Meade but I've got a ton more research to do before I'll move forward with anything. Like trying to see differences in Equitorial vs Fork mounts. Even started thinking about how in hell I'd unload that 14" if I could manage to swing it.... the tube alone weights 120 lbs....LOL.

Is there an extender one could use like the 1.0x flattener, 0.8x reducer, that would give say a f/10 and allow for a full frame camera? All the extenders I see use eyepiece fittings. I want a focal extender I can use in front of any diagonal, for camera or visual observing? Why do not find anything like that for any scopes? But many scopes have reducers specific to them? No scopes I find have extenders specific to them or made for full frame imaging?

The Askar V has an extender, along with a reducer/ flattener and a flattener and two different objective lenses that you can use with all three optical accessories. Oftentimes extenders can degrade image quality considerably. At least that’s what I’ve seen when it comes to them with cameras (teleconverters, specifically). But if well made, they can be great still.

@@SarahMathsAstro Wow!!! Thanks for pointing that out! The Askar V is GORGEOUS! If they had an optional 100mm and/or 120mm objective for that I would be very tempted to spend too much money on that! I think the 103 APO is already over my current budget, but I may have to just go with it anyway! I just wish the 103APO had the very classy silver accents, not a huge fan of the orange aluminum, silly, but I care too much about design aesthetics! Anyways, maybe while I wait and save money for my next refractor, maybe Askar will make larger aperture options for the, or like the current Askar V?? Oh, and yes, in my experience teleconverters for camera lenses are a compromise, but generally the lower extension work well, but higher extensions like 2.0x can degrade enough that it's not much better than cropping on the image file. But camera lenses are already very complex with a ton of optical elements. Given the more simple, highly optimized for sky distance subjects telescope options, I would hope extenders designed for a scope would perform well. Maybe for AP people just use smaller cameras? For visual people just use barlows? It's disappointing it seems the flatteners, reducers, extenders seem made for camera use only and you can't use them for visual observing? I don't understand why exactly, just mechanically you can't put eyepieces or diagonals on the end?

Apologies for not explaining further. Pinched optics is a type of distortion that is usually due to the objective lens of a refractor being secured too tightly with screws. When the objective lens are secured too tightly, they can cause these weird defraction looking spikes through large, bright stars. I wasn't 100% sure of what it was though since it can be challenging to really nail down a cause of something like this. But it can be corrected for by loosening the screws which I am going to try once I get some tools.

Has anybody ever asked you about problems and how to resolve the Problem of Newtonian Telescope 8 inch, I know you have sponsors and impromotors on your it's not possible to answer the question thank you for listening.

Most of my experience is with refractors and SCTs. I would post a question in the forums of CloudyNights.com though - someone with your specific telescope may be able to help out better.

Excellent job doing the video…..so how about doing something using the telescope and not just a review on equipment

Thank you and thanks for your feedback/ idea too!

1k$ isn't even close to budget unless you are rich. There are offerings for less in the refractor category but at this PO nt you might as well get a good reflector so you at least get more scope for your money.

Yeah i hate it when people in this hobby say things are "budget" and they are over $1k. Newtonians for life!

What the heck are "pinched" optics??

@SarahMathsAstro

For a refractory, pinched optics could be caused by retainer rings for example. Colder temperatures make them more pronounced. I'm still not sure if this is pinched optics though.

So the retainer ring is actually so tight that it's differetially compressing the lens glass??@@SarahMathsAstro

2nd askar scope review where I've seen pinched optics. Not good and definitely gives me pause buying this brand.

Yeah, still trying to diagnose if it was for sure pinched optics or maybe a bolt or something in the OTA somewhere sticking out. This is a pre-production version so maybe that has something to do with that. I think a lot of the other scopes that are reviewed, at least on YT are also pre-production units.

Take off the dew shield from the OTA and twist the front end lens just a slight bit

What happened to good old visual observing? Nowadays, it's all about astrophotography. Astro youtubers are all above astrophotography. So frustrating for someone like me who refuse to go digital. I want to see the stars in the skies, not on a monitor screen.

Keep complaining, if you want a scope for observing you'll either get a reflector or a dobson. Theses scopes are made with astrophotography in mind.
