Description
If you are needing a faster version of your ZWO FF65APO Quad, this reducer will take your f/ratio from f/6.4 to f/4.8.
ZWO has released a brand-new FF65APO 0.75 full frame reducer with a four-element optical design. It has a reduction factor of 0.75x, which gives the FF65APO f/6.4 astrograph a shortened focal ratio of f/4.8 and a shorter focal length of 312mm. This allows for less total integration time and a wider field of view, bringing more convenience and possibilities for your wide-field deep sky imaging. The back focus distance is the standard 55mm. It also comes with two thread adapters of M54 and M48, and a built-in M48x0.75 2 filter thread, which makes the connection work simple and convenient. Connecting to the APO is fairly simple. Unscrew the eyepiece holder on the end of the focuser, then simply thread the reducer in its place.
