SV503 102ED Telescope - SV193 Focal Reducer With SV188P Diagonals For Visual Observation
Much better optical quality and performance
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.
Suitable for planetary photography
I bought this exact OTA a month ago and I tried planetary photography and the results surprised me a lot.
High performance and well-build quality
I bought the SV503 80 and I'm very happy with it's performance and build quality.
This scope will make your astrophotography a real joy
I have the svbony 503 80ED and the sv550 122mm, I started astrophotography seriously at the end of last year.I'm a real fan of the Svbony brand.
Best choice for both visually observing and astrophotography
The SV503 telescopes are awesome for this price-range. And especially the 102mm is the best choice for both visually observing and astrophotography.
Excellent ED doublet refractor
I own this 102ED myself, and I am planning to add a mono camera and filters ouch instead of getting a triplet/APO
Suitable for beginner astrophotography
I purchased the 503 80ED last year after having entered into AP and had no idea what a doublet was. I found that the quality was great considering it was my first refractor.
The performance for visual astronomy has been great.
I bought the 102 version last month. I'm under Bortle 8 skies, so even my C6 has contrast issues . Yet, the Svbony, under full magnification 200x (using your favorite Baader Zoom and barlow set) at Jupiter and Saturn worked very well.
