Fantastic Telescope, Incredible Price!

Z-Field on May 21,2024

The image of the Moon is a composite made from two images taken with the SvBony SV305 camera then stitched together for the full image. It created some excitement on Facebook as it shows a lot of detail you would not expect from a telescope of this size. The image of Venus was also taken with the SV305 camera. The third image of the solar prominence was taken with a 4x Powermate Barlow, a Daystar Quark Hydrogen-Alpha filter and a QHY174GPS camera. It was a composite of two images, one of the prominence and the other of the sun’s surface. The camera was monochrome so color was added. This telescope is a solar and lunar imaging machine! WARNING: Do not use to view the sun without proper filtering as permanent damage can occur to your eyes or equipment!

Excellent ED optisc & focuser

Christopher Anderson on Apr 19,2024

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.

Good quality without breaking the bank

Daniel Martinez on Mar 23,2024

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

Much better optical quality and performance

Malik Johnson on Nov 14,2023

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

Javier Torres on Nov 13,2023

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

Richard Miller on Sep 15,2023

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

Tyrone Carter on Aug 16,2023

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

William Garcia on Jun 14,2023

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

Shanice Williams on May 09,2023

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

Ryan Jones on May 04,2023

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.

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.
