SVBONY SV193 2" 0.8x Focal Reducer /Flattener for SV503 80ED Refractor

Description: SVBONY 2" 0.8x focal reducer and field flattener for refractor telescopes Optimized for use on the SVBNOY 80mm f/7 ED refractor and similar telescopes The 0.8 times defocusing system shortens the exposure. It can meet the needs of astrophotographers who need sufficient exposure in a short time. With advanced refractor, it can take dazzling celestial photos without worrying about the distortion of the star points on the edge of the photo. Multi-coated optics housed in a high polish, and hard anodize finished aluminum body to help reduce weight. Includes standard 2" filter thread to add light pollution filter you need. The front end is a standard 2-inch socket to connect to the main lens, and the back end is M48x0.75 threaded to connect to the camera bayonet (Support Full Frame Camera) Designed specifically for SV503 80mm f/7 ED Refractor. The field flattener corrects the inherent spherical aberration of curved lenses which causes distortion at the edges of the field of view. As a focal reducer, it reduces the focal ratio of the scope which translates into wider fields of view with shorter exposure times—allowing you to capture more images in the same amount of time without sacrificing performance.
