PRODUCT DESCRIPTION
The ZWO F65 Reducer is a 0.75x full-frame reducer designed specifically for the ZWO FF65-APO telescope. This four-element optical design reduces the focal length from 416mm to 312mm, and the focal ratio from f/6.4 to f/4.8, allowing for faster imaging and a wider field of view.
With a back focus distance of 55mm, the F65 Reducer is compatible with full-frame sensors up to 44mm in diameter. It includes M54 and M48 threaded adapters and features a built-in M48x0.75 2"" filter thread for added flexibility and connection simplicity.
Ideal for deep-sky astrophotography, the F65 Reducer enhances the FF65-APO's performance by reducing exposure times and providing a broader field of view, making it an excellent choice for capturing expansive celestial objects.
