SVBONY 2 Inch 0.8x Focal Reducer / Flattener for SV503 102F7 f/7 Refractor

 

Features:

1. SVBONY 2" 0.8x refraction telescope has a focal reducer and a flat field, which can meet the lighting requirements for full-frame photography.

2. With SVBNOY 102ED, the focal ratio is shortened from F /7 to F /5.6. Focusing allows you to take a wider view of the sky, with finer points and a better signal-to-noise ratio at the same exposure.

3. With advanced refractor, you can take dazzling celestial photos without worrying about the distortion of stars at the edges.

4. Multi-layer coated optical elements are installed in a highly polished and hard anodized aluminum body to help reduce weight.

5. Includes standard 2" filter threads to add the light pollution filters you need.

6. The front end is a standard 2-inch socket to connect the main lens, and the back end is M48x0.75 thread to connect the camera bayonet (support full-frame camera)

7. The default rear intercept is 55mm. Use the 360° FIELD of view rotator (sold separately) at the end of the focusing tube to satisfy your composition requirements without turning the main lens, as well as the filter wheel /OAG/ astronomical camera
