It was a great scope to get me hooked on the hobby!

Chris M on May 21,2025

My first scope was the sv503 80mm f7, and it was a great scope to get me hooked on the hobby! Now i have the sv550 80mm, sv550 122mm and sv555 54mm. All are great budget scopes!

Absolutely recommended for visual astronomy!

Thomas on May 19,2025

Everything great so far! The quality and optics of the SV503 80ED absolutely amazing! I love it!

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.

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 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.

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.

I don’t feel I need anything more fancy than this!

Joseph on Feb 23,2025

I bought this sv503 80ed scope and 0.8x field flattener as well as mini sv165 guide scope one year ago as my first astrophotography rig and I have been very happy with it.

Nice gear I've own

Isabella Ruiz on Feb 08,2025

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

This is a great little telescope.

Robert Stout on Jan 14,2025

This is a great little telescope. Far better than the entry level title people give it. The build quality is excellent and it is good value at the price. I ordered the telescope direct from SvBony on December 26 and it arrived well packaged at my address in the UK on January 6. I have managed (between clouds) to do some imaging and I am very happy with the results. Based on my experience I would definitely recommend this telescope. I am hoping this company will venture into harmonic drive telescope mounts.
