Superb price/performance ratio
I owned a 102/1000 mm F10 Bresser achromat for some time, now I purchased the Svbony 102mm ED FPL51 and its significaltly better with a lot less chromatic aberrations. I like this refractor a lot, especially because it's sold for an excellent price
Worth a look as a first scope.
I have the the 80mm version of this scope. I think for the price it's very good. It's not as good as a triplet but the difference is not big, mainly slight halos on bright stars. It's well built and nice to use. I have the reducer for it as well. It's my go to scope and I really like it.
this was the best rig I could afford
This is the exact telescope I use with an ASI2600MC. With a 0.8X FF/FR and a Pegasus Focus Cube, this was the best rig I could afford.
Best price with high quality
I have the 102 and the 70 and I love them! Glad at got them before the tariff war being in the states!
This sv503 did really surprise me
I purchased the 503 102ed during the Black Friday sale with competitive price. Thanks svbony. I can proceed my hobby.
Nice gear I've own
I got one sv503 telescope a few months ago. Pretty happy with it.
For me anyway it was money well spent.
i have the 503, 102 for a few years now and i really like it, i use it with my asi 585 and it produces images i am happy with for the price of the setup. it seems to be a good match for a smaller censor i think most people buying a cheaper beginner telescope like this are not going to have an expensive apc sized cooled camera anyway. the chromatic aberration is a pain but it can mostly be sorted out in pixnsight.
Excellent ED optisc & focuser
I have the 102 mm ED verson from Svbony. I have used it for visual observations and photography, it's very very nice for the planets and the Moon (with filter) clearly better than my Bresser 102/1000 mm achromat. It also has an excellent focuser.
Good quality without breaking the bank
I've been using this scope for almost 2 years. Primarily DSO astrophotography with some visual use. I have zero complaints.
Much better optical quality and performance
I own the Svbony 102/714 mm for 6 months now, previosely I had a Bresser 102/1000 mm F10 achromat and the Svbony 102 ED has a much better optical quality and performance. Also the 2 speed focuser is infinitely better than the ones used on simple achromats.
