Hi, I started AP last year and have 3 scopes now and still use my ST80 to this day. A few notes about the ST-80: 1. My dew shield gets off of mine, but i think i have the older model 2. To reduce gradients, a good and easy tactic is to color the side of your lens with a black permanent marker. 3. I needed to add an extension to my camera to be able to get proper focus. 4. it's 100$ frikin dolla 5. I have been able to produce nice images, most problems can be treated in editing.

Great review. I used to have a 12" Dobsonian and a small refractor for my children when they were young 25 years ago.

Thanks again.

Now that SVBONY has released their SV550 APO triplet for around $800 it would be a great comparison to add to this. At half price of the Askar, the new SVBONY triplet seems a great value.

[@old_guard2431]

Very good review. Drawing analogies to conventional camera optics: 1. Two elements corrects chromatic aberration (color fringing) for two out of three colors to be “achromatic” but adds no correction for coma (triangle effect near the edges) or field flattening. The SVbony does an amazing job of bringing the third color into correction. 2. Add a third element, and you add correction for flatness of field. With the “field flattener” the SVbony becomes in effect a three-element lens. 3. Four elements gets you spherical aberration correction, a fully-corrected achromatic or something approaching apochromat with ED glass, depending on who is in charge of the definition. Limiting maximum aperture and keeping focal length in the normal-to-long range for the format minimized spherical aberration and field flatness issues for the simpler camera lenses back in the day. Seems like Orion did a pretty good job with the test scope considering the wide aperture. Better for direct viewing with a decent eyepiece than photography, clearly.

[@backgammonbacon]

Hi Nico, your content just gets better and better. This really does make it clear what you are getting for your money and just how much of an improvement you get from ED glass compared to an Achromatic telescope. Looks like people will get great results from that Svbony without needing to break the bank. I honestly think this is a massive service to the community and in hindsight its a really simple idea, just show what each telescope does with the same target. I recently tried to do mono imaging on a skywatcher startravel telescope, rebadged orion so same scope, and I could just not get rid of halo's on blue filters so sort of solved the question of "Can mono imaging cure the deficiencies of acrhomats?" with a resounding no, even using narrow band OIII filters couldn't cure the blue issue. Would be nice to see what the Svbony could do in mono imaging too does that bring it up to the level of the Ascar? Welldone!

The SVBONY from Hong Kong is an emerging giant killer in this highly competitive amateur astro area. All their accessories also are very good from a price to performance ratio. SVBONY and ZWO products make a wonderful starter kit with a good GEQ mount thrown in. HEQ5 is my preference.

Great video. As a photographer, I have the following question: how do these telescopes compare to a decent 500mm F8 mirror lens (e.g Minolta, Tamron or Nikon, not the el-cheapo mirror lenses) you can get for many cameras?

[@NebulaPhotos]

The f/8 will be a drag compared to the f/4-f/5.5 range of these scopes for deep sky work (you will need about 2x the total integration to match signal to noise ratio). I suspect that star performance will be better than the Orion, but nowhere near the Svbony. Usability would be worse than any of these: harder to stay in focus (no locking nut), no included mounting points or hardware.

I would love to see you do this exercise but compare one telescope (80, 120, 150, C9.25 ect) against a couple different size sensors (Full frame, ASPC, IMX533) . I am curious to see what effect different sensor sizes will have on the field of view. I think this could help with choosing my next camera. I have my eye on the 2600 right now because I would like to get a wider field of view for larger targets. I have a Esprit 120ed and a C9.25. I am also shooting with the asi533 mono and the asi294 One shot. Would my money be better place getting a good 80 like this ASKAR or is the camera the more versatile choice.

As with all things size and quality matter.... In this comparison all 3 have same 80mm diameter. Engineering, material, quality of components all make a big difference. You explained this technical topic is understandable terms and had good examples. I have been looking around for a suitable telescope and this video was helpful.

[@JonnyBravo0311]

I really like that Askar scope... a bit slow natively at f/7.5... but that's pretty much my only gripe with it. Quadruplet design... good rings / bars with plenty of mounting points... beefy focuser... brings a lot to the table for a $1750 price tag that _includes_ the 0.76 reducer. I own a GT81 and it requires a flattener of some sort. WO sells the 6AIII which is a combined reducer/flattener. They do not sell a non-reducing flattener, so you'd have to get something like the Stellarvue if you wanted to run the GT81 at its native focal length. I like the simplicity of being able to use the Askar scope without any additional components or having to worry about whether you got the spacing right. If I were looking for an imaging scope in the 80mm aperture range, the Askar would be pretty high on my list.

[@ChainsawFilms]

Right now Amazon's page for the 503 says there's a new version of the 503, and it links to the 550. Are they discontinuing it? It's $389 USD right now, and the 550 is $699.

I'm in the same boat. Just be aware, a lot of the low cost mounts only have 11lb capacity. After that they get up to $800+. So the scbony 80ed will need a bigger mount. And you'll be spending $1600+ easily for all of it. I'm considering the 70ED, so I can get a cheaper mount. Also check out William Optics. APO and much lighter doublet.

I can't say I've seen anyone imaging with a Sigma FP before either, that was interesting, plus I'm trying to work out what camera you're filming on as the grade almost has that Black Magic look about it?

[@stefanweilhartner4415]

the sigma fp has a great dynamic range suitable for good video recording

[@NebulaPhotos]

Thanks! I did pick up the Sigma fp because I was interested in both it's video and astrophotography capabilities. It is a neat camera, but has some usability drawbacks, so it won't become an everyday camera for me. Since May 2020, I film my youtube videos (including this one) with a Canon EOS Ra. I usually use an RF 16mm lens stopped to f/4 in 4K crop mode which does a 1.8x crop in on the center of the sensor, giving the 16mm more of a 28mm feel. I shoot in Canon Log and do a very simple grade in Final Cut Pro.

[@douglassmith1215]

There is an error in the drawing at 3:00 of the video. The lens diagram of the 80PHQ is incorrect. The two outside elements of the front triplet are ED glass. The single corrector lens further back is not. Also, the shape of the rear corrector is not accurately drawn.

[@n-da-bunka2650]

The # of ED glass DIRECTLY relates to the costs. The field flattener is essentially "built in" to the triplet so... if you have less $'s just buy a good doublet and then add the field flattener. Essentially, you get "what you pay for". Been an AP guy for a while now. My SW 100ED was $900 when I bought it but now goes for around $1,300 so it slots between your top 2.

I have a NextStar Celestron 6 that's almost twice as much as you most expensive one. I got it from my brother before he passed on [he was going to get a better one] and haven't gotten the tracking to work with the star align. You have to use three bright stars but 6 times in a row "alignment failed" is displayed. I live on a mountain at 4K feet which provide perfect atmospheric conditions but unfortunately have a limited field of view due to pine trees. I thought about connecting a DSLR to it but haven't researched it since it has standard eye piece optic holes. After he passed on I got some real expensive eyepieces he had kept for his to be new telescope. I'll have to wait for summer again when it's warmer and commit myself to operate it in the early morning hours before the sun comes up because here in Northern California that is when the brightest stars come up so I can see if I can get it to align with those bright stars that are sure to be in the database. I know the database is in the motorized pedestal because you can align it with the hand control even though you can use a smartphone app connected via WiFi which is actually easier.

I don't understand the point of using a full frame camera on an 80mm ED rather than APS-C on a 60 mm ED? You pay extra because the scope can handle full frame, you pay more for the longer focal length, the full frame camera costs more, the entire set-up weights more and you end up with the same FOV?

I personally prefer doublets with high quality glass, (Stellarvue Access and AT72EDII), but would really like to know if it's worth the investment for a triplet. Thanks!

Thats a good point! I got recently an RF 800 F11 for wildlife... not really though about astrophotography, but somehow as i tried the moon i realized - it looks sharper, especially at the corners than my 750mm F5 newton. The F11 is very limiting when it comes to longer exposures where my newton on EQ mount shines... but its "usable" on a cheap startracker... and adapted to the equatorial mount.... the RF 800 F11 is a SUPER LIGHT WEIGHT ASTROGRAPH! I replaced as much as possible where the RF 800 made sense (so widefield, non cropped images) my 750mm newtonian. Just a charme, especially with startracker i have my astrophotograpy gear in a small backpack and its even possible to go hiking with the 6-7kg around (most weight comes from the sturdy tripod...)

considering the svbony is FPl-51 doublet and the Askar is a Quad APO, the results would be between those 2 scopes for all the testing. The Askar is impressive but the little svbony actually looks really good for the amount paid. Your doublet with "high quality glass" would fall somewhere between the svbony and the askar, so is it worth it to you ? ( I would think not a much better image than the svbony but a little better, but not as good as the askar. )

@@batsonelectronics But how much better than the FPL-51 and how much worse than the Askar? What's better, what's worse? Images tell the story!

[@batsonelectronics]

@@JohnRichards_Astro are you really serious ? You saw images of a mid range scope and higher end scope and you think the little bit of difference an upper mid range might be cannot be seen by the example of mid to high ? He compared a 150HP and 300HP car to an identical one with 400HP and you want to know the speed of a 350HP car by comparison. It will literally be in the middle of the 2 better scopes tested here.

I spent $400 on a telescope Didn't realize I would want $1000 of lenses and filters lol, but it was a good time. I remember seeing the Andromeda galaxy for the first time. This was before you could hook up a laptop to it (I had find it all manually). Knowing how far away it was and being in the middle of some field 1 hour south of town on a brisk late fall night. I got SO weirded out. It just looked like a smudgy finger print, but dang. so cool. Best telescope night ever.

Very informative comparison, thanks. It would be interesting to se Vixen ED81S with flattner and reducer compared to the Askar. But I guess you can’t test all scopes. Keep up the good work!

[@philipfletcher4867]

would not the right filter change the difference between Orion and Svbony and Svbony and Askar?

[@JoeBob79569]

100% agree about not skimping on the mount! Every time I see people asking this I say the same thing to them, that you can have the best telescope, camera, and everything else in the world, but with a crap mount you will still get crap images. As well as the fact that I'd much rather have two telescopes and one mount, than have two mounts and only one telescope. In fact that's why I'm here now, I'm thinking about about getting a better scope, because I spent most of my budget on a HEQ5 last year and cheaped out on the scope, and I don't regret it one bit.

Quality work Nico.
