Is this the BEST small ASTROGRAPH I've ever used? In-depth HONEST review of the Askar SQA55!

[@CuivTheLazyGeek]

The Askar SQA55 is a small Petzval design astrograph that gets amazing star shapes across a full frame sensor... AND offers great mechanical and quality of life features on the scope itself.

[@derekbaker3279]

I'm not trying to be a argumentative jerk here, just sharing what I have learned from evaluating optics for 50 years, i.e. my thoughts, for what they're worth....for your interest, especially if you are relatively new to astronomy.... No, it isn't perfect. For starters, as is the case with all Askar optics, there is noticeable chromatic aberration, even in the APC sensor. This indicates either a very poor design, or more likely given Askar never reveals the glass they use, they use cheaper quality glass than most manufacturers. FYI, not only does that mean that the colour correction is not optimal, but it makes me wonder if the homogeneity of the glass is sub-standard (which will affect things like opacity of the glass), if the coatings are on all surfaces, and if the coatings suppress reflections over the entire spectrum that CMOS sensors can detect. (..in fact, it is possible that some of what looks like chromatic aberration is actually internal reflections in the deep red/near IR and/or violet/near UV ends of the spectrum..) Also, as Cuiv pointed out, his test with the full-frame camera was not very discerning, because the pixels are 6um wide, versus 3.76um in the APC camera he used,. I seriously suspect that testing with an ASI6200MM Pro or other camera with 3.76um pixels would reveal even more issues near the sizes & corners of the frame. Having said that....while any aberrations, poor colour correction, lower than optimal opacity, and internal reflections do reduce contrast & increase the true f-ratio...it is pretty clear that the lens does produce very good results that are more than sufficient for the vast majority of imagers, especially if they factor in the enticing price. Cheers, Derek

[@jimmazurek5589]

I am using the Askar 180 Pro, which has similar features and quality. It’s the perfect travel AP scope. The people at Askar really know what they’re doing.

[@CuivTheLazyGeek]

Yep, they seem to have cracked the code to manufacturing and assembly tolerances too!

[@rinceart]

Very nice scope. But, the choice of a helical focuser is kind of unfortunate (as well as the aperture adjustment ring; although you can just leave that open). I understand they were going for a telescope/camera lens combo, but I have a hard time seeing its usefulness. Even William Optics moved away from this concept. Otherwise, it is an excellent telescope.

[@CuivTheLazyGeek]

Since filming the video, I negotiated to buy my sample, and also bought the EAF kit - it works beautifully and the belt tensioner is excellent, so while I agree that I prefer R&P type focusers, this helical focuser doesn't bother me at all in the end!

[@rinceart]

@@CuivTheLazyGeek you're completely right. It is not a deal killer by any means, more like a minor hindrance. :) But, say what you will about WO (I am not a huge fan myself), their internal focuser is quite nice. I would be all over an SQA55-II with a similar internal focuser, no aperture adjustment, and perhaps a little bigger image circle to cut down on that pesky vignetting (even though it is easily correctable).

[@svfixerup]

I choose to purchase this scope over the new redcat 51 gen 3 do to the flat field and sharp stars seen on the edges especially in this price range. Some of the images on astrobin with no post processing are very impressive. My askar sqa55 is on its way. I do have a question though.

[@AndyLucy-z3x]

If you put a bright star in the corner, using an APS-c sensor, the image shows some aberration (faint cut-outs in the star shape, caused by aperture vignetting). For Astro work, it’s best to tape up the aperture ring, since it can be inadvertently moved (been there, done that, got the (unwanted) starburst effect) The fine focus ring has 1/10 the sensitivity of the coarse focus ring. Overall results are very good. Use 2x drizzle with BlurXterminator and the results are outstanding, revealing excellent detail across the whole field.

[@CuivTheLazyGeek]

Awesome to hear - and good idea on the aperture ring!

[@blufferblue1599]

I hope they sent you SQA 106 as well. It looks to have better stars at the edge of the Medium Format camera, than most scopes have in the middle, which is kinda nuts. Oh, and great review Cuiv, thanks for the amazing work!

[@geomark8851]

While you are at it, we would also like a review of the SQA 85. Not much on KZbin so far but everyone has them in stock. I'm guessing Askar has not sent them to the usual reviewers and it makes me wonder why they haven't especially when the price is taken into account.

[@roopey]

Yeah camera lenses can be anything. It's crazy. It almost feels like a scam. Worst of it all is that they can do an excellent job, if they want to.

I had to choose between the Sharpstar 61edph iii and the Askar FRA300. I went for the faster optics of the 61edph iii, but something like the SQA55 seems like a great upgrade in the future. I really can't do the belt EAF system as I pack my gear in a backpack, but hopefully we see something similar with a different focuser in the future. It's also great that Askar/Sharpstar is really dropping the price point for great optics. I haven't seen price adjustments yet from other manufacturers, but if they want to stay competitive they're really going to need to make some changes. Although the optical quality isn't on the level of the SQA series, I still can't believe you can get a solid 140mm triplet from Sharpstar for the same price as a 120mm ED doublet from Skywatcher. It's a great time to be in the hobby.

What do you think about the Askar FMA180 (not pro)? It is a tiny (40 mm aperture) triplet apo and comes with a full-frame flattener/reducer. Without that, the telescope can be used with a star diagonal and eyepiece, or a 45-degrees Amici prism and eyepiece, or a Herschel wedge and eyepiece (or camera). It seems to be very versatile.

Hi Cuiv, another great review. Looks to be a great piece of kit but I wont be buying one. I don't doubt its performance but I think the small refractor end of the market is pretty saturated at the moment. At the end of the day this is still more or less an f5 scope. On the few nights a month that I can image from where I live, it is rare that the sky is clear enough to image for more than about three hours a night, with an f5 scope it can take up to to two months to capture enough data to produce a reasonably noise free image, so in my case my next scope will have to be something a lot faster, I'm beginning to think that something like a C8 with a hyperstar might actually be a better fit for my own circumstances, I just wish there was more competition at this end of the market.

Hi Cuiv. Awesome as always. So one weird question. Sorry if this is a dumb question. I understand the Askar SQA55 Quintuplet does not require a field flattener. However, could it still be used with a reducer? If so, do you know of any reducers that might work with it?

No, I don't think it can be used with a reducer - I think F4.8 is pretty good already, if you want F4.5 you'll need to look at the SVBony SV555!

[@ferenc-x7p]

At this point, with what we have, I don't think it's economically efficient to buy a doublet or even a triplet in this size (50-60mm). Just get this, or someone on a budget, get the Svbony SV555. Don't bother with doublets and triplets and mess around with backfocus issues, and still dealing with F5.9 (at best), while these scopes are a full F stop faster! Not to mention the hidden cost of the flattener. Now I feel like, getting a full frame camera starts to make sense😊 , it's just my bank acct. that went on strike. 🙄

Excellent test, thank you! I have an SQA55 as well but I’m not seeing anywhere near the level of vignetting you are showing. I see just a minor level of vignetting more in keeping with Askar’s promised specs on field illumination, which claims only a 10% falloff at the corners of a full-frame sensor. You are showing much worse vignetting even on a cropped frame camera, and uneven with the right side much darker than the left. As it is, your results are contrary to Askar’s promised performance, and any difference between promised and actual performance is just what a review should point out. So what might be the explanation of the vignetting you show? It can’t be just sky gradients from your urban site? It would be “enlightening” to find out! Thanks! I enjoy your reviews as they are always thorough and cover products we often don’t hear about in North America.

[@CuivTheLazyGeek]

Remember that I'm using auto stretch! Different levels of auto stretch will show different levels of vignetting, and exaggerate differences, it's a map transfer function (so you can't say anything conclusive from this video - tbh I never consider vignetting to be much of an issue for me) The proper way of measuring would be to use flat frames and look at the pixel values - I'll do that for my next scope review!

[@cjermo]

Thanks as always Cuiv! Different scopes, obviously, but how much better (or worse) does it perform against the Askar V with the 60mm reducer, giving about the same focal length?

Hi Cuiv, thank you for another awesome video! In Australia, ASKAR SQA55 is $1300, the SVBONY SV555 is $800. Is Askar worth extra $500? I was thinking of getting Askar but $500 extra is kinda a lot. Cheers mate

[@CuivTheLazyGeek]

I think the SV555 would be enough for 80% of people!

[@Byaltair]

@CuivTheLazyGeek thanks mate

[@mevansmrichard]

Oh, good, a telescope that’s sealed tighter than my weekend plans. Because the real enemy of astronomy is air? LOL

[@christophdunkel1562]

Thanks for the review. Theoretically, if the SQA106 would be the same, would it be better or worse than an FSQ106EDX4? Or is the FSQ still in it's own class?

[@blufferblue1599]

On paper it's better than Tak. However no reducer for the Askar is out, at least yet, for those crazy F3 speed.

[@christophdunkel1562]

@@blufferblue1599 that is exactly what I thought. The thing is, I do not see any of these chromatic abberations on any of my Tak pictures. Hence my question. Always on the hunt if something better is out there. But in this case I fail to properly understand it yet.

[@CuivTheLazyGeek]

I wish I could get my hands on a Tak like that :)

[@vmh104]

Hi Cuiv, As Always very grateful for your videos. Quick Question: It's older brother the ACL200 has an odd quirk in that the entire front of the telescope (lens) moves when you (coarse) focus. (I did not realize till I made a triple scope setup and made a bracket to hold the front of the scopes together. My painful lesson ;) ) Is it the same with the SQA55 (it's hard to notice if you're not looking for it) Thx!

[@CuivTheLazyGeek]

The front of the SQA55 does move, so it's not fully itnernal

[@PaMalacrida]

Any suggestion for a similar quality OTA in the 400-500mm range? I have seen Askar has a 85 version but we also approach the 3000 $ range 😢

[@artyombeilis9075]

What would you recommend for wide field but for smaller sensor size - I don't need APS-C - just basic sensor and fast scope? I've read about EvoGuide 50 + flatner but it seems to have problematic focuser with huge backlash.

[@CuivTheLazyGeek]

Would work great with a 294 of 533, still gives you so good FOV!

[@artyombeilis9075]

@@CuivTheLazyGeek are you talking on this scope? Obviously it would work with smaller sensor. But it comes on premium.

[@ricklaird2218]

great reveiw

[@LukeKwan78]

are there refractor scope that have a faster aperture? my sony 70-200 and 300mm lens are F2.8. and my 600mm is F4

[@efx245precor3]

Might want to use higher f ratio for planetary just guessing

[@ACKitsBilltheCAT]

I was wondering if you think that the case could conceivably be modified if one was to install an EAF? I understand that with the standard foam and OTA orientation there isn’t physical room for the EAF. Is the interior foam removable from the outer case? If the OTA turned on its side and the foam was fully replaced, would everything fit in your opinion? Just curious. BTW - love your channel!

[@CuivTheLazyGeek]

mmmmmmmmh maybe? But I think the fit is too tight

[@thimitri1]

OMG I am going to have to reprocess ALL of my photos from the last couple years. I was watching you check the edges of the image for star shapes and you kept saying (almost disappointedly) saying "perfectly round" And I'm thinking to myself, aren't they a little oblong? THEN I PUT MY GLASSES ON. Sheesh... I've been throwing out perfectly good frames (I'm new to glasses BTW, but I've needed them for a couple years at least) Great review. I already have the RedCat so.... ¯\_(ツ)_/¯

[@CuivTheLazyGeek]

Oh man that's something I would never have thought about! Well have fun reprocessing ;)

[@-Jeremiah-]

@ on the plus side I might get an all new set of pics from this realization! Hahaha thank you for that!

[@luboinchina3013]

How does it compare to SharpstarEDPHIII? I am constantly amazed by its quality. Have you still got it?

[@luboinchina3013]

Recommend with 1.0 flattener

[@CuivTheLazyGeek]

I had the EDPH II (the one Trevor's scope was based on) which is completely different from the EDPH III! I've actually never tested the III, so I can't say much about it. The II obviously had the horrendous CA issue I had found, but that was fixed by a free objective lens exchange program, but otherwise was a good little scope!

[@luboinchina3013]

@@CuivTheLazyGeek I really recommend the iii version with 1.0 flattener . It really is amazing. Something to compare and review.

[@Alan-vk6bk]

I think I'll start saving my pennies 😉

[@CuivTheLazyGeek]

Good idea :)

[@bad_metaphor]

Still see CA but better than the SV555. The astrobin samples look good too.

[@CuivTheLazyGeek]

Yeah this one is really a keeper

[@petesastrophotography]

Excellent review as well Cuiv. Looking forward to playing with this scope, I ordered it before I even got to the end of Luke's video :)

[@CuivTheLazyGeek]

Thanks Pete!!

[@CuivTheLazyGeek]

Thank you so much!

[@toneotoneo]

What happened to the sv555? 😬

[@CuivTheLazyGeek]

As I mentioned in the review video, it was on loan for review and so I gave it back. I kinda sorta purchased the SQA55 though :p

[@toneotoneo]

Yes but a direct comparison with the little svbony would have been nicer ...the redcat was a lost battle already..btw since you are there a visit to starbase would be ideal with the direct prices they have there 😬

[@toneotoneo]

I have an opportunity of an oldy sharpstar 65q ed at 300usd used what do you think?

[@peter26514]

sounds cool, but isnt a sub 1000 € lens kind of "underpowered", considering the rest of your gear (camera and mount) cost like 5 times as much?

[@CuivTheLazyGeek]

It's a great widefield lens/scope, would pair great with an AM3 + 2600MC Air for instance! Now I'm curious about the SQA85 and SQA106!

[@terrizittritsch745]

Hi Cuiv, another great review and based on what you said previously, I'm going to do something I don't usually do and that's buy a telescope based on a youtube review. I usually take a while and multiple data sources to make decisions as it's still in my DNA being a retired engineer. But based on the fact that dingdong running the country next year is at least threatening tariffs, which means price increases, and I've needed a wide field imaging scope for some time, I ordered one through your channel. If it doesn't work out you'll be the first to know :)

[@CuivTheLazyGeek]

Oh wow! I really hope it works out! For now, it does look like reports from the wild are very positive - and you're right, with looming tariffs, the time to stock up is now...

[@IIKings211]

My data sources indicate the economy will be much better, which means I'll have more $$ to spend on AP 😂

[@efx245precor3]

Focuser could be more EAF friendly.

[@efx245precor3]

Oh I thought you said that was the sv555

[@brianhayward8240]

When I first saw the thumbnail of the vid, I thought A55 was a 3 letter word.

Ha! :D

[@sianikolaou5440]

The only negative is that you have killed the chance I will ever buy a RedCat!

[@CuivTheLazyGeek]

Hahaha sorry about that!

[@fenice319]

the one downside is that I can't afford it T_T

[@CuivTheLazyGeek]

:(

[@davidemancini7853]

I have heard this word “ cheaper “ too many times with this product, in my opinion it is not! Many users will upgrade the focuser with the ZWO EAF and got to buy a guide scope too so this scope will cost you at least 500$ more vs the RedCat come with a proper focuser and guide scope too. So in my opinion is not worthed buy this product just to have perfect round stars LOL considering we have many software that solve that problem……

[@CuivTheLazyGeek]

Thanks as always Marvin!

[@TheCongratulationsChannel]

This 'telescope' looks like a camera lense - especially the lense cap. Looks like I can stay with my Canon EF then.

[@CuivTheLazyGeek]

Lenses are telescopes and vice versa :) I've never seen an AF lens as good on a star field as this particular refractor, even my 300mm f2.8 closed to F4 wasn't as good! But yeah for many people AF lenses is all they need!

@CuivTheLazyGeek he's a sell out. I stopped watching his videos after he showed off opt and their raptor nonsense.
