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

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.

I have the 102 and the 70 and I love them! Glad at got them before the tariff war being in the states!

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.

I purchased the 503 102ed during the Black Friday sale with competitive price. Thanks svbony. I can proceed my hobby.

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

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.

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.

I've been using this scope for almost 2 years. Primarily DSO astrophotography with some visual use. I have zero complaints.

Just a quick review for anyone wondering about this scope. First impressions are excellent build quality. Critical items like the focuser and dew sheild are near perfect. The Focuser has just the right weight and zero play. I can bring my DSLR to focus with the draw tube at 65 mm - the focuser is easily strong enough to hold it in position. Colour correction? First look at The Moon and Jupiter - there was no CA. But when I video through the scope with camera phone then yes you can see CA - the camera of course can see into the Ultra-Violet Spectrum unlike the human eye. I bought this scope for visual, so I'm super impressed with an ED Doublet (I also wanted the Doublet for its lightness) that shows no CA visually at the same price as an achromat. I've looked at The Moon, Saturn and Jupiter at high power - 223x (8-24mm zoom with 2.5x Barlow) and views are outstanding. I can't help pass a glance over the 122 mm - LOL - but now for now the 102 ED is ruling the scope shed.
