- ED Glass structure: The doublet air-spaced achromatic design with S-FPL51 ED glass reduces chromatic aberration, delivering crisp, accurate color images;
- Large aperture for bright images: The 102mm objective lens with an f/7 focal ratio brings more lights into the scope body and you will get more bright and clear image;
- FMC-coating for crisp image: Ultra-wideband multi-layer coatings and a retractable lens hood provide bright, wide-field images with sharp resolution, perfect for various types of observation;
- Dual-speed rack focuser: The 90mm back focus and dual-speed rack and pinion focuser with focus knob cover make it easy to achieve fine, accurate focus for both visual and photography.

Extremely well made and nice features
i have bought the SV Bony 102mm f/7 size last week -just waiting for good seeing conditions, all extremely well made and nice features
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
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.
Wonderful
I bought this scope over five weeks ago and wished to share my experience with you.
Wow, this telescope really delivers excellent views. I can honestly say that there is no chromatic abberations what's so ever either low or high power. I have had the best views of Venus, jupiter, mars, star clusters and nebulas I have ever seen in my life. The planets all showing increadable details in fact, I recently took mars upto x350 for great details that I wanted to knock on my neighbours doors and drag them out to have a look but reality took hold and I said to myself that they would not understand. I have been stargazing for well over thirty years and have had dozens of scopes. I currently have a 127mm maksutov telescope and 90mm doublet refractor and the svbony sv503 102mm ED totally blows them away. This scope is a keeper and want to say a big Thank you to svbony for a wonderful telescope.
Easy to maintain. No calibration or corrections
I have the 503 102 for over a year now, and I love it. I also have newtonians and SCT's but the SV503 have become my primary telescope. I use it for astrophotography only. I can recommend using a MONO camera and HA, S2 and O3 filters. You will be amazed with the results. Best thing is the SV503 is very easy to maintain. No calibration or corrections. Just point and capture, and explorer the universe.
The 503 102 is a good choice.
The 503 102 is a good choice. It is just big enough to enjoy some details in distant DSOs and small enough to get a decent field of view as well. Alternatively, I have opted to not use the reducer/flattener to maximize focal length for some targets as well.
Pretty good
I have tested it's SV503 102mm refractor. Pretty good, stars are sharp and round everywhere. Light weight too .
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.
GREAT VALUE !
Great scope for Astrophotography beginners. It is well constructed and made solid. It's compact. Easy to breakdown, pack it up and move around. However, I only had once chance to use it since received. Mostly cloudy nights, not good for observations. During the one night used, it performed great with my onboard planetary software, PHD2, Sharpcap and CDC. I was able to capture the M42 briefly as a test run. It turned out well for the first time. This is a great scope considering the cost. I was looking for something that wouldn't break the bank. I'm totally satified with it. I went further installing the ZWO EAF auto focuser. It works great and perfect match for the scope, easy to install.
The ZWO ASI533 mc pro camera is compatible with the scope. Perfect match.
I highly recommend this scope for beginners, like me!
