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

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.

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 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.

Good quality

Brennen Robison on Oct 30,2024

I use the SV503 70 ED. For around 300 dollars it's been an absolutely amazing scope, I've managed to produce some good images with it. I know a doublet isn't for everyone, but on a budget, it's minimal quality sacrifice for saving a couple hundred bucks instead of a triplet in my opinion.

Perfect

luke kimuyu on Aug 12,2024

This is the first new telescope I've ever brought and it is perfect at the box my only issue is the dovetail is just a little bit small full telescope over wise performs perfectly to this day and I would have had it a year in November I need to used pretty much every week and lives outside permanently

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.

Exceeded expectations

Mike Lynch on May 28,2024

This 102mm f/7 ED refractor is worth well more than I paid for it! The first time I took it out for a night of observing the sky, the sharp, contrasty views of star clusters and nebulae impressed me and my observing buddies. They spent as much time looking through this scope as through their own, much larger, reflector telescopes. The objective lens gives wonderful views. The "mechanics" of the scope are well-made and put together, including the retractable dew/light shield at the lens end and the rotating focuser assembly at the eyepiece end. Two small quibbles: The main focuser is a bit tight to turn, but another owner tells me it will loosen as I use the fouser. (The fine-focuser worked very well right out of the box!) There was no user manual or documentation include with the telescope. But I found some pages of information and directions, particularly about the focuser, at a Svbony page online. I plan to use this refractor purely for observing, not astro-imaging.

Features

1. The appearance of the telescope is baked with high-end fine-grained paint, with exquisite appearance and delicate feel;
2. The objective lens features an S-FPL51 extra-low dispersion glass ED element, which eliminates chromatic aberration. This results in the best color correction for an ED doublet lens
3. The lens adopts optical processing and low polishing technology, which is carefully carved;
4. The deceleration ratio of the two-speed 2'' toothed focusing seat is 1:10, which makes it easy to achieve accurate focus;
5. If the 70ED is matched with a large chip, A possible way is to: The SV193 increases the field of view of the shot, which is sufficient for most DSOs. The stacked image edges may need to be cropped in the post-process to improve image quality.
