sv503 prime focus- Connected to M48 Camera Ring photography, also known as direct focus photography, is a method of directly using the telescope to take pictures without adding any optical objects between the telescope and the camera.The main objects of prime focus photography are nebulae, clusters and galaxies.This can be achieved by matching the sv503 set with the M48 camera ring.
Best Budget Doublet astro telescope!
The SV503 doublet scopes really do offer some fantastic views, especially for beginners.
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.
