Peek into the home of any advanced amateur astronomer and you’ll be surprised not only at the number of telescopes but that there will almost always be an 80mm telescope and you might be more surprised that it is the most used. Every telescope has its advantages and the 80mm is a perfect size for taking wide area images of the night sky. Many objects in the sky are actually quite large and require a small telescope to image, see the image of the North American Nebula attached. An 80mm is also the perfect “Grab and Go” telescope for when you want a quick view of something but don’t want to setup the “big” telescope. Every astronomer has a small telescope they can use on a tripod when they want a quick look at something. I’ve had this telescope a little over a week now and I’m quite impressed. If you are just starting out this is a telescope you can grow into and not out of. It is light weight, only 6.3 pounds, and will be at home on a tripod as on a telescope mount. For the more advanced amateur, this telescope is an astrophotographer’s dream! The image below is of the North American Nebula and though you can see some coma near the corners, it has over a degree of tack sharp star images. The image of the Galaxy M101 was taken a few nights later with a HoTech SCA Field Flattener and has over a degree and a half of coma free area. These were taken with a cooled IMX294 camera and is a stack of 70 two minute exposures stacked and processed in PixInsight. It was taken from a light polluted suburb of Dallas during full moon, the North American Nebula was with an Optolong l-eNhance filter and shows what can be done with a good telescope even from a big city. For those just starting out getting an image this good can take some time. The image of the Moon is a composite made from two images taken with the SvBony SV305 camera then stitched together for the full image. It created some excitement on Facebook as it shows a lot of detail you would not expect from a telescope of this size. The image of Venus was also taken with the SV305 camera. The third image of the solar prominence was taken with a 4x Powermate Barlow, a Daystar Quark Hydrogen-Alpha filter and a QHY174GPS camera. It was a composite of two images, one of the prominence and the other of the sun’s surface. The camera was monochrome so color was added. This telescope is a solar and lunar imaging machine! WARNING: Do not use to view the sun without proper filtering as permanent damage can occur to your eyes or equipment! Who should get this telescope? Those in astrophotography who need something with a wider field of view, people wanting to view the sun (be sure to use an approved solar filter) and the moon. You can also see star clusters, nebula and some larger, brighter galaxies. You can certainly view the planets through this telescope, but the short focal length makes it better for wide field objects. If you are a beginner and are looking for a good telescope that you can use later for astrophotography then this is a great scope to start as you will not outgrow it. You should note that the telescope only comes as an Optical Tube Assembly, you do not receive a star diagonal, eyepiece or finder. That is typical of high end astrophotography telescopes. If you are just beginning you will need a SVBONY 2 inches 90 Deg Dielectric Mirror Diagonal, a set of eyepieces, a red dot finder and base, and a large tripod or telescope mount (iOptron SkyGuider pro, iOptron CEM40 or Celestron VX mount for example). I would recommend also buying a 2” extension tube such as the Orion 5124 2-Inch Telescope Eyepiece Extension Tube or the Explore Scientific Rack and Pinion Focuser 2" Extension Tube - ESRPEXT2 if you want to do astrophotography. I found only one minor complaint and that is the focuser. Unlike the description, it is not a Crawford style, but a rack and pinion, the latter being the standard for most telescopes. That isn’t a big deal, but for astrophotography a Crawford is preferred. The focus is a bit spongy, but still quite usable. I was able to add a motorized focuser and, while there was some image shift while focusing (as is usual with all rack and pinion focusers), it was still easy to reach a good focus. The image of the North American Nebula was focused by hand. Like almost all astrophotography refractors, an extension tube (mentioned earlier) is needed when using a camera. Not a big deal, but it would have been nice to have it included. I was able to compare this telescope to another 80mm ED f/6 scope from another company that costs twice as much. The SV503 was as good if not better in almost every respect. The image in the SV503 was brighter, even though it is an f/7 and the other scope was an f/6. The only reason might be that the other scope has three lens elements while the SV503 has two and that resulted in more light being absorbed. Still, it was surprising. Both telescopes had about 1.1 degrees of coma free field of view. The SV503 was lighter than the other but was a bit longer. Both telescopes had a way to rotate the focuser to allow for better framing with a camera, but the SV503 was much smoother and had a better locking mechanism than the other telescope. Both had rack and pinion focusers and both had similar focusing characteristics. Between the two the SV503 was the clear winner even without the cost differential. Pros: 1. Incredible price, about half what other 80mm ED telescopes sell for 2. Perfect for beginners and advanced amateurs alike 3. Bright, wide images, superb telescope for astrophotography 4. Tack sharp over 1.1 degree, even more with a field flattener 5. Focuser rotation is super smooth Cons: 1. It is listed in the description as a Crawford focuser, but it is Rack and Pinion. It still works quite well. 2. Focus extension tube not included. Not a big problem. Should you buy this telescope? Definitely! In fact, the friend I had help with the image of the North American Nebula and M101 likes it so much he buying one for himself. ... show more

    • GREAT VALUE !
Size: 70mm
Great scope for Astrophotography beginners. It is well constructed and made solid. It's compact. Easy to breakdown, pack it up and move around. However, I only had once chance to use it since received. Mostly cloudy nights, not good for observations. During the one night used, it performed great with my onboard planetary software, PHD2, Sharpcap and CDC. I was able to capture the M42 briefly as a test run. It turned out well for the first time. This is a great scope considering the cost. I was looking for something that wouldn't break the bank. I'm totally satified with it. I went further installing the ZWO EAF auto focuser. It works great and perfect match for the scope, easy to install. The ZWO ASI533 mc pro camera is compatible with the scope. Perfect match. I highly recommend this scope for beginners, like me! ... show more

With a field flatiner that is speced for the scope that brought me down to F/6 @ 480mm of focal length. I'm new to astrophotography and have pulled off some crap data shots that equal a person that has 5 years in. So the scope is excellent.

    • Very Good Scope at a Great Price

The SVBony SV503 is a very good small ED refractor at a very attractive price. I purchased it primarily as a "Grab & Go" visual scope, but it appears well suited for astrophotography as well. I've only had the opportunity to use it once so far for viewing the moon. Yes, there was a very slight color fringe on the moon's limb, but it was not disturbing. In general the view and moon detail were excellent. I pushed the magnification to over 100x and there was no breakdown of the image at all - not bad for an 80mm scope. Since the SV503 utilizes an objective doublet with one element made from Ohara FPL-51 ED glass it is not a true apochromatic scope. There is some chromatic aberration (CA) on bright objects, like the moon, but it appears to be minimal. The optical tube assembly (OTA) is very solid and well made with three internal baffles. It has a built-in dew shield that is retractable for easy storage. The focuser is a 2", two-speed fine pitch helical track rack and pinion (R&P) style that can rotate 360 degrees for better framing of photographs or more convenient viewing if mounted on an equatorial mount. My scope arrived with significant backlash in the coarse focuser adjustment. This is not a cheap or bad focuser, however. There are several 1.5mm set screws on the focuser that control the alignment and tension of the focuser mechanism. Although these are not meant to be user adjustable, I found the correct set screw and I was able to slightly tweak it to completely eliminate the backlash. I have another scope with a true Crayford style two-speed focuser and after adjusting the SV503 R&P focuser it is virtually every bit as smooth and free of play or backlash as the Crayford focuser. The R&P focuser helical gearing also eliminates the "creep" that can occur on a Crayford style focuser that has no gears and relies solely on friction to move the focus tube. Overall the fit and finish of this scope is excellent - nothing appears to be "cheap" on this OTA. It has the "feel" of a much more expensive instrument. I deducted one star from this review due to the out of adjustment focuser and the fact that it ships with absolutely no instructions or user manual - in fact no paperwork at all! Some scopes of this class come with a storage case, but at a much higher price. I was able to find a very nice third party case (sold by Amazon) at a good price that suits this scope well. As a Grab & Go scope the SV503 is exactly what I was looking for and I may even try some astrophotography with it. {Note in the attached pictures the case and accessories must be purchased separately and are not included with the SV503.} Pros: Excellent price for an 80mm ED scope. Good ED doublet objective lens. Retractable dew shield. Good Helical R&P 2", two speed focuser. Focuser can rotate 360 degrees. Both the 2" focuser and the included 1.25" adapter have compression fittings. Light weight (OTA, tube rings & mounting plate weigh 6.2 lbs). Nice metal lens cap. Good fit & finish. Cons: Scope arrived with focuser out of adjustment. No included storage case (but third party cases are available). No included instruction manual, user manual or warranty card. Some slight CA, but this is not unusual on a short focal length ED doublet design. ... show more

I bought this during Prime Day and was a little concerned about the optical quality. But I ended up being surprised by how good everything looked through this telescope. With good eyepieces, there is literally no chromatic aberration visible and the image is sharp from edge to edge. Also, the build quality of these telescopes is amazing. Highly recommended! ... show more
