Product Description
The ZWO F65 Reducer (0.75× Full Frame Reducer) is designed specifically for the ZWO FF65-APO refractor telescope, giving astrophotographers a wider field of view and significantly faster imaging performance. By reducing the focal length from 416mm to 312mm and the focal ratio from f/6.4 to f/4.8, it captures more sky in every frame while shortening exposure times. Its premium four-element optical design supports full-frame cameras with a 44mm image circle, delivering sharp stars and excellent edge-to-edge image quality for deep-sky imaging.
