The ZWO FF65 APO 0.75× Full Frame Reducer is designed specifically for the FF65 APO refractor.  It has a reduction factor of 0.75X, which shortens the effective focal ratio to f/4.8 for a wider field of view and shorter image acquisition times.  The reducer has a four-element optical design and will work with full frame cameras.

The back focus distance is the standard 55mm. The reducer comes with an M54 and M48 adapter as well as a built-in M48x0.75 2” filter thread.
