Deep sky photography OTA
The SV550 APO Triplet refractor with 80mm aperture and fast f/6 focal ratio, a great travel telescope for observation and astrophotography.
4 extinction bars are designed to meet your ultimate pursuit of extinction.
Hollow-out standard dovetail plate
The distance between the 2 hoops can be adjusted according to the rear end load to achieve the balance of the whole system
Extreme extinction process
4 extinction light bars are used inside the lens barrel, which can eliminate all stray light interference on the inner wall of the lens barrel
2.5" dual-speed rack-and-pinion focuser
10:1 ratio fine focusing with M63x1 female thread for adaptions
The 2.5-inch focusing base can effectively reduce the vignetting problem when connecting to a full-frame camera, and the FPL51 APO can improve the quality of the captured images.
Magnesium alloy focusing seat, compared with aluminum alloy materials of the same specification, the weight can be reduced by more than 20%, reducing the load
Lens design: triplet apochromatic optics
triplet apochromatic optics
The triplet apochromatic optics structure (1 piece of S-FPL51 low dispersion ED glass + 2 pieces of correction glass) is adopted to significantly improve the image quality of the captured image (15.8% increase by the spectrometer calculation). Significantly reduces edge dispersion resulting in blue fringing problems

Great little 80mm APO.Views of the Moon showed absolutely no color fringing whatsoever, very impressed. MY new Grab 'n Go scope. Will update review when I get to use it moreGreat optics and great value !!Second small SvBONY scope I have bought, excellent optics on both.

Ordered the SV 550. Received it a couple of days ago. I inadvertently ordered the 80 mm instead of the 122 mm. It was my mistake.Although I had initially desired the 122 mm, I was impressed with the ease of set up and the quality of the 80 mm. I had always used Different types of scopes, including the rasa, and a couple of SC 8’s etc. . Nothing was easier than setting up the telescope with an Orion eq 26 mount. I was very impressed with the visual and a brief session of photography with using zwo 2600 color. I incorporated an ASI air, electric auto focus, Lens flattener (not a reducer), , backspacing, scope camera…etc. It was a very nice neat package that fit in my gym bag! It was approximately 14 inches long by about 9 inches high. I didn’t weigh it but I suspect somewhere around 11-12 pounds. I can now “go lighter” and feel confident That I did not make significant sacrifices. Something that I’ve been looking forward to for sometime.I think I’m keeping the 80 mm.This is an update: I ordered the 122 after having decided to keep the 80 mm as well. The 122 came double packed and inside the second box was neatly placed telescope in a well packed carrie bag.I have only set it up on the mount now but it’s like dad and little boy. Although the 122 is quite manageable, It does weigh twice as much as the 80mm but still keep it in the range appropriate for medium capacity mounts.I am putting a Dual scope mount on my AVX and will be able to use both telescopes simultaneously for camera, viewing, or any combination of both.The combination of these two triplets, ais a. great value and compared to the price of a single Rassa 8., I believe I have a true value in owning both of these scopes.

Pro build quality, similar to William Optics.. I have an older 90 Megrez, both very nice scopes. I enjoy viewing, no astro-photography as of yet.. but I've seen very nice pics from this 80mm triplet online & read good reviews. I ordered the package mid-Feb w the OTA/tube-rings, soft case, 6x30mm finder/bracket & the 1.25" mirror diagonal w red anodized sides. The dew shield fits snug & moves free w no slop. Focuser is 10:1 ratio heavy duty, well built & smooth. The finder shoe/dovetail bracket may moved from one side to another 10 or 2 clock position.. also has sub-positions to fix it on either side w machined grooves on the housing. The paint, fit & finish are all superb, no flaws. The optics I tested on 1 good night- Jupiter, the Orion nebula & lastly the moon. I could detect no false color on any object at any time except a slight blue haze before it cooled down outside.. 44deg. Very sharp optics, I used multiple power EP's & a barlow in later. Diffraction rings looked sharp inside of focus, a bit fuzzy outside.. read this could be slight spherical aberration. The details on Jupiter were impressive.. the moons, belts & red-spot neat to see. Overall I'd recommend this little triplet to anyone looking for portability & quality. I mounted it on an AstroTech Voyager alt/az mount I bought years ago.. enjoyable to use in tandem. I'm testing a few other Svbony products soon- relatively newer business since 2018, 7th anniversary - I've been around the hobby for about 30yrs. JB

It's easy to pay over 5000 dollars for APO triplet refractor. When SVBony offered one for under 1500 dollars, I was skeptical. Yet, reviews were excellent. I could not pass up the temptation to purchase the SVBony 550 refractor. I could not be more please with my choice. There is zero chromatic aberration, even on the planet Venus. Images are extremely sharp. Focused stars show textbook perfect diffraction rings at high power. Planetary images are incredible. The cloud belts of Jupiter exhibit bewildering detail. Also, I love the exterior fit and finish. The focuser is extremely robust. It. can easily support the heaviest 2" eyepieces, as well as the heaviest, full frame 35mm digital cameras. If you want to enjoy top performance in a 5 inch refracting telescope, look no further than the SV550.

Very nice triplet for a reasonable price. Quality seems very good and focuser is accurate with no noticeable backlash.

Beautiful telescope. Quality is excellent. The support re parts on Amazon is poor. They should just jack the suport parts up. Costed weeks and baught wrong items to try to get from 2" to 1.25.

This triplet APO refractor gives me crisp stars. Good DSO images. The only complaint is that the dovetail plate needs to be longer to achieve balance with a DSLR.

The build quality is superb, the optics are bright and sharp, the focus mechanism is extremely solid and smooth. The entire assembly is much more solid that it appears to be in pictures. Definitely a higher end scope. Pretty thrilled with it so far.Edit—After getting some more clear nights boy this thing performs beyond expectations, I’m imaging with the ASI2600MM pro in mono with it and wow, pinpoint stars across the entire feild, no aberration noticeable at all. This scope is the deal of the century. If you’re on a budget and looking for a very high performance APO for astrophotography then it can’t be beat there’s nothing I’d complain about. I mounted it to a Losmandy rail to add room for power supplies and my imaging computer. I still haven’t had enough clear night to really push it to it’s limits but having taken some images under less than perfect conditions the results are impressive to say the least…
