This type of video is so important. Nowadays the social medias and forums are full of people who spread so much misinformation and make beginners much more confused. I have a WO Z61 and I'm so happy with that. But when I asked on Facebook groups about this scope. Many people said stupid things like doublett are terrible for astrophotography and I should not buy it etc.

I image with an Astrotech 80ed doublet. Yes there is a bit of CA. Does it cause a huge issue? No. My next scope will be a quadruplet, but there is absolutely nothing wrong with imaging with a doublet. Great video as always Nico.

[@mfaison]

The worst thing about Galileo's telescope wasn't the chromatic aberration, but the tiny, tiny exit pupil, due to using a concave (diverging) eyepiece. This made it look like you were viewing through a straw. We have a replica of Galileo's 30x telescope, and it's crazy to compare the view of Jupiter or the moon through the replica and through a cheap 90mm refractor. It's amazing that Galileo could discover anything with that thing!

Really useful comparison Nico. Thanks for taking the time to do this. My first telescope was an Orion EON 110mm doublet, bought 2 years ago. At the time I really hemmed and hawed over doublet vs triplet. Triplets were so much more expensive. Still happy with my decision as the optics are very good. Now I’ve added the WO ZenithStar 61. Nice little wide field scope. Dr B from Manitoba, Canada 🇨🇦

[@ycanerol]

What a fantastic video! This hobby really benefits from these type of data-backed comparisons, and I really appreciate that you are producing such comparisons with transparent disclosures of where the telescopes come from; such integrity is rare to come by these days. Another aspect which might not be apparent is that you switched the scope three times, during each imaging session to keep the test consistent; while most of us are barely managing a single set up! I for one am backing all the way off once I confirm the test shots look okay, let alone change the telescope after 50 minutes :D, kudos Nico!

[@Jaymz007]

Excellent video Nico! I know I had a discussion with you about the Askar 80 but ended up going with the Askar 65PHQ with the reducer. It worked out to be a bit better for the focal length needs. I am so happy with the scope. My only beef is the focuser is just a bit stiff on it. Not terrible both other than that, it really does a great job at color correction and has a super flat field. The reducer does a great job and doesn't detract from image quality. Best bang for the buck in my opinion! Cheers

This is a great video. It's important we get comparisons between similar hardware in one video. The Astrophotography community really needs an Rtings like site that will put the scopes through a battery of tests to verify manufacture claims and to disclose the quirks of use. Use a dial indicator to measure focuser slop, both side to side and in-out for use with an EAF. etc.etc. Mounts as well..

[@markmayer9290]

Great comparison as always. I'm very happy with my WO triplets plus flatteners. There's a much better option for dealing with inserting filters, which as you show is quite difficult for some of these scopes: a filter drawer (e.g. from ZWO). Fits right into the standard 55 mm back focus requirement, and swapping filters is super easy, without disturbing your imaging train.

[@stanmacdonald1073]

Thank you for your effort and clear, dark nights to test and put together a documentary on these scopes. - It is interesting to see how little the differences are between these scopes. The main difference appears to be the diameter and perceived brightness of the stars. They particularly difficult to compare because amount of stretch will vary with the exposure. - One possible solution might be to only integrate 2 or 3 images from the faster scopes to match the signal to noise ratio of the images and stretch the stars so their peak brightness match using the same transformation curve.

The tripet objective or more elements in the objective can also correct for secondary axial color. Also axial color can blur the spot decreasing the contrast before you can actually see the color change in the spot.

[@hunterwells7647]

Great review! As far as cost goes, at 4:50 you mentioned that these prices include the field flatteners, but the links in the description for the William Optics scope bring the total to over $1000.

[@kevinashley478]

Hey Nico. Your videos are an absolute go-to for anyone just getting into the hobby or someone thinking about getting into it. And you have covered reflecting and refractor telescopes in-depth, and the different camera types as well. Could you do a video on what I call the mash up telescopes, like Richey Chretien Reflecting and MAK, and SCT (although isn't a MAK just a sublevel of the SCT? )?? I have been looking at a few MAK's and they seem to be more along the lines of what I want. Good for astrophotography and visual. I think it would be very helpful to do a video reviewing those three, pros and cons, and what separates them from what I would call "classical" telescopes.

[@NebulaPhotos]

They are popular telescope designs for solar system objects (sun, moon, and planets) both visually and photographically. The typical issue with these telescopes for deep sky astrophotography is they are usually slower (f/10+), and can be fussy to collimate. I might get to them eventually on the channel.

[@MacM545]

Fascinating! Did you ever get a chance to compare any such scope to a larger reflector and/or Cass-type scope? It may also be quite interesting to see what difference there is, although I am not sure what exactly a fair comparison would be regarding what size difference there'd need to be between the reflector or Cass and the refractor..

[@carlosespada6202]

good analysis. Thanks

[@BennyColyn]

The loss of star color in the last scope is at least in part due to the stretch PixInsight uses in its ScreenTransferFunction (it's basicly a HistogramTransformation) - a color-preserving stretch with ArcSinh or Generalized Hyperbolic Stretch will show that the stars very much still have color (until you burn out the core)

[@NebulaPhotos]

Great point! I thought about cutting that out because I realized it was sort of silly to be judging star color on the auto stretch for the exact reason you mentioned.

I am actually going to run my first sessions with a wide FOV on my 105mm F2.8 Nikon lense.. cost as much as the telescope but is really a great lense I use regularly. I already have plenty of SBC (raspberry pi) that I have installed "astroberry" on and have been working with a number of different software combo's.. Seems no one has a lock on this part of the hobby... I am now trying to find where you buy "clear sky" time.... I called the city... no go.... .

Great, thorough review as always, Nico. Terrific. I didn't see that the IR-Cut filter you used from Astonomik has a very different profile from the IR-Cut filter used on the ASI2600MC Pro. Was there a reason you chose to use this for your OSC images? Loved the review! Thanks again for the hard work and time you put in for this, Nico.

[@NebulaPhotos]

Yes, old habit as I used to never be able to remember which Astro cameras have IR cut and which just have clear AR windows so I almost always use one, but in this case wasn’t necessary as the ASI2600MC does use IR-cut as most the modern models do.

I really wish more people would do honest reviews like these. They are really helpful and feels trustworthy. As someone who also has the Sharpstar EDPHII, my experiences are pretty much the same as yours (elongation in the corners, even with the reducer/flattner). The telescope is probably decent enough for its price, but I think the design of the reducer and the image quality is a bit meh compared to other, similar telescopes.

Excellent little scope that literally almost fits in your pocket! I have it and I used it already once, unfortunately I can't buy clear skies and it's been very rare this last 3 months! Don't underestimate that tiny scope! It has a better corrected starfield than many camera lens that cost 3x.

[@fgandola76]

First of all, thx a ton for putting that together. this is extremely usefull, especially for me who is still on the beginer side, and was wondering this exact same question about the usefullness of triplet APO vs a simple doublet while shooting narroband..I am confused with something though: you mention in your test testing Doublet but as you say later in the video you tested the williams optic with the extra flattener, which makes it doublet from a chromatic perspective but in essence a triplet but i am fine with that other than you could have mentionned the extra cost i suppose. My question is more about the Sharpstar. It is presented as triplet APO. If i understand well its design, from a chromatic perspective it has 2 optical elements, and because one is ED then is can be called APO. The third element is the flatener, is that correct ? Now for the review result, do you have an explanation about the fact the quintuplet works better than the doublet + flatener ? is it link really to the fact it is quintuplet or could it be quality of the maker that makes the diference. If you get the opportunity, i d love to see the same test with same manufacturer doublet + flatener and quadruplet or quintuplet ;-) Again thx a ton for sharing your experience !!! (i apologize for potential inacuracy, i am no expert...)

[@thierrycombot7110]

I am quite interested by your comparison as I could be interested by the 65 phq. In your video, you said you would made the image files avalaible. Will you put them on your website? It would be interesting to compare the FWHM obtained by the telescopes. In particular the 65 PHQ seems notably superior, and it seems that after resampling the image SNR would be comparable to the fastest scope, EDPHII. Also, for these short focal lengths, using a camera with 2.4 um sensor could be interesting, as they are even more picky on the telescope quality, especially on axis (they are small diagonal sensors)

To be honest, looking at the last comparison pictures (13:26), it seems like the quintuplet really shows not only much sharper stars, but the DSO itself, while all other scopes (they're of very similar performance) produce somewhat soft-feeling images.

Thank you very much for making this Comparison video. I have the William Optics 72mm Doublet. I haven't used it yet. But I believe that William Optics OTA ED APO Doublet can hang with the Quadruplet, and Quintuplet with ease. The Triplet does have a wider Field of view. But the clarity is not as good as the Doublet, Quadruplet and Quintuplet. I believe that it's really not worth buying the other OTA's unless you are buying a faster and larger OTA. I think that the clarity from the William Optics OTA ED APO Doublet is Amazing. Thank You again for making and sharing this video out. Clear Skies. Michael.

Hi, the small rotator with screws on the reducer (second telescope) makes sense, because if you screw your dslr on and it is in an awkward position, you can adjust it once. You don't need to use the main rotator with the focuser and turn it to an awkward position. Regards Andreas
