Great
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
