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.

Agena Astro and High Point Scientific are the main US Online Retailers. But the Svbony scopes also sell on Amazon and eBay. Check the description for links.

[@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.

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!

[@beenaplumber8379]

I am torn between the Svony 503 and 550 80mm now. I can get a flattener/reducer for the 503, I don't have to pay extra for the camera rotator, it's $300 less, but the 550 is a triplet! 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.

[@matthouben4242]

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.

Thank you for this eye opening comparison. For an APS-C shooter the Svbony seems to offer very good results.

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. I guess what I am asking is to actually see the effects of image scale.

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.

[@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 picked up the SW .80 flattener, ASair Pro, 2 ZWO cameras and use an HEQ5 mount. Just found your channel and have now SUBSCRIBED

[@mercury7]

We are at a golden age to where you can buy a nice refractor for under a grand, only caveat is quality assurance may be off so be sure to purchase from a reputable dealer so you can return if you get a lemon. Not all scopes come out the same in mass production, two otherwise identical scopes may perform differently…. Higher priced scopes normally weed these out in the QA process while lower end ones may slip through. Try to educate yourself on basic star test so you can immediately tell the difference

Just purchased the Askar with the reducer. Looking forward to see the difference of the pictures and clarity from the Radian 61.

[@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.

[@HAYDS510]

This video was perfect for where I'm at.

[@MegaMichaeltodd]

One thing I've often wondered and have never had a satisfactory answer to is the difference between these types of telescopes, would it be it so large if you were shooting in narrowband? My suspicion is that they would be much closer in performance. Thus, if you were shooting in narrow band you could save yourself a lot of money compared to broadband

[@nimeq]

I think the reason you haven't gotten a good answer is that it it's problematic. Just for a specific narrow band of light you could make the optic shorter with materials or lens design and get rid of the ED glass, but the entire lens design would be specific to the band. So price would have to reflect the design costs, manufacturing.

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.

Another great video by Nico Carver! It's interesting that you picked a full frame non modded camera for the comparison. 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?

[@andreoliver5927]

Just a suggestion. I bought the Rokinon 135 MM F2 lens for my Sony. I'm curious as to how it compares with the SVBONY SV503 80ED Refractor Telescope. They are the same price. I know the focal length is different but for instance - is the Rokinon a doublet or a triplet? Also, is the lens as well multicoated as the telescope? You do great reviews, BTW.

Now he is interested in using it again, but can't find all of the parts. It was a decent sized hobby telescope with an electric drive for locating celestial objects, but had no accessories for capturing images with a camera. I'm still looking through boxes trying to find all of the parts, but I might end up helping my Son, who is now 30, purchase a new telescope for us both to use and I'm interested in researching more info about the digital all-in-one telescopes, as well as looking into the possibilities of DIY optical telescopes. Is there such a thing as a DIY telescope? Something where you buy some high quality lenses and build a really long collapsible tube, or is that just a really stupid idea?

[@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.

[@desbarry8414]

You should know as well as I do that SEEING and local conditions play a bigger part in the overall result than the difference between an FPL53 doublet or a FK61 triplet lens configuration. I learnt this very quickly. That's why I bought an Altair/Astro Tec 115mm with FK61. Still a triplet but with slightly less expensive glass as my seeing is average. A waste of money to buy an expensive triplet if you r seeing is average or below.

Brilliant comparison Nico! So useful for people to see side by side exactly what they're getting for their money. I think one take away is that you can get away with a relatively affordable ED scope if you keep to APS-C or M43 sensors (That Askar is stunning though!) 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?

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.

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...)

[@batsonelectronics]

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. )

This was an awesome, educational video. I certainly understand this comment will be cringy... but as a complete novice.. I was like " but I like the cool blue and purple colors"...

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 use a superzoom camera, its about $400 and all corrections are included, and the sensor, and you can get 1200mm+, plus I use automated stacking.

IF I had it to do over - simpler issues than this video - started with a ' department store (useless, primarily because of the tripod ) 3 inch, then a 4.5 inch Newton which was useable, spotting scope was not, tripod still shaken. then I finally got an 8 in. Dobsonian, great, steady base, 2 inch focuser, 50 mm spotting scope. problem, it's too big for me ( I'm 73 ) to easily move in/ out. IF I could start over, it'd be a 6 in Dob. with computer control of some sort.

Great Video as always! Thanks Nico!

[@stanimal8]

I'd love to see a test on the Askar 71f flat-field, quad element APO refractor. Seems like its value vs performance ratio might beat these 4 scopes by wide margins.

[@liamstrain]

Excellent break down, Nico. Definitely gets into diminishing returns with the higher investment - but still quite clear.

[@badebadeston575]

Now, this is a great comparison!

[@anvikshiki]

Your videos are incredibly informative and helpful, so thank you for all the great work! The Askar design seems great. I'm thinking about the 107 rather than the 80 though (I already have a WO Redcat 71. Trying to figure out what kinds of FOV the 107 would offer for galaxies. Anyway, outstanding content, thanks again!

[@NebulaPhotos]

Everything I've tried in the Askar PHQ series has been great so far! For visualizing the FOV of the 107 with different DSOs, you can use telescopius.com or my favorite is Blackwater Skies Imaging Toolbox: www.blackwaterskies.co.uk/imaging-toolbox/ I have a short tutorial on using it here: kzbin.info/www/bejne/nYPHZJKoqN-jgas

I once owned a vortex binocular and thought i overpaid, i returned it and bought a Bushnell for half the price with good reviews. It was not as good, but better than half as good. So the value debate is was I happier with a better value (ratio =performance/price) , nope i think i should've kept the vortex. As with all optics satisfaction comes with a painful price.

[@gregorysamaniego36]

Finally someone to explain now what's the smallest one I can use to see galaxies

[@NebulaPhotos]

You can see the brighter galaxies like the galaxies in the Messier catalog with any of these. If you want to photograph them, these would work fine. If you want to view them at the eyepiece, I'd suggest a dobsonian telescope, bigger the better.

[@russianhomecat3313]

I think you should use images of planets to demonstrate the difference. Nebulas and stars look pretty the same

[@ralfg9194]

Good explanation. Very helpful. kind regards from Germany!

[@yoops66]

Probably my first time here. I'm interested but not that much: I looked at the video for roughly 20 seconds at the start, and about 3 minutes at the end, for the comparison. Still, this video is valuable as hell. Thumb up.

[@AmatureAstronomer]

I just bought an SVBONY SV503 Telescope, 70ED F6 Extra Low Dispersion Refractor OTA and the associated SVBONY SV193 Focal Reducer and Field Flattener from Amazon. Will arrive this coming Thursday. It will be replacing my GSkyer short tube 80. Looked at the 80mm, but it was too heavy and the focal length was too long. I wouldn't be able to photograph everything I wanted with my ZWO ASI183 camera. Appreciate your videos. Informative.
