ZWO Full Frame 0.75x Focal Reducer for FF65 Telescope
Model: zwo_ff65_reducerPart Number: ZWO F65RE
ZWO has released this new FF65APO 0.75x 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 includes two thread adapters, M54 and M48, and a built-in M48x0.75 2” filter thread, which makes the connection work simple and convenient.
