Superb price/performance ratio

Joseph Davis on Apr 11,2025

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.

Jamie G on Apr 08,2025

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

Michael Brown on Apr 08,2025

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

Joseph Davis on Apr 08,2025

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

DeShawn Washington on Mar 14,2025

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

Isabella Ruiz on Feb 08,2025

I got one sv503 telescope a few months ago. Pretty happy with it.

For me anyway it was money well spent.

Brian Lee on Aug 04,2024

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

Christopher Anderson on Apr 19,2024

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

Daniel Martinez on Mar 23,2024

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

Malik Johnson on Nov 14,2023

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.
