Bargain triplet, don't forget the flattener for it.

This is a bargain 80mm triplet meant for astrophotography. Produces excellent images with the right camera. If you want to make it faster and wider field of view for your camera, get the reducer that is made for the 80mm doublet, it works 100%, just like the dedicated flattener for the triplet. Highly recommended.

80mm Sv550 Triplet APO

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

A Great Scope

After owning a SV503 (102mm) for several years, I decided to go for a triplet and little bigger for imaging. I have a tight budget and after some searching I opted for the SV550 (122mm). The SV503 had served me well for several years so it came as no surprise to find the SV550 also to be of very solid build and very smooth operation. The first images it produced with an ASI071MC Pro gave nice sharp stars with no evidence of distortion close to the edges. It has only been a few days since its arrival but already I am very impressed and have no regrets about the purchase. An added bonus is the fact that it arrived at my home nearly a week ahead of the predicted date. I look forwards to many years of astrophotography with it.

Great little telescope

I'm not 100% sure why I bought this telescope. I was going to buy the SV503 80mm F7, but when I came to this website, I saw the SV550 and something told me to get it instead. It's F6, which is pretty fast for such an inexpensive telescope. It arrived a few days after ordering- again, surprising since it came from China. The box was heavy- much heavier than expected. I've owned "cheap" 80mm ED refractors in the past. Let me first say, this telescope might be inexpensive, but it certainly isn't cheap. It is very solid, very rigid, very well made. I got the optional rotator and field flattener as I am using it for imaging. Stars have been spectacular edge to edge. My stars are coming in at 1.2 FWMH during electronic focus! Pretty amazing. I would highly recommend this telescope to anyone, beginner or experienced user. I don't even own an EP, so how it does visually, I don't know. But as an astrograph, it works amazingly well. I look forward to many years with this scope.
