ZWO FF65 APO 0.75× Full Frame Reducer

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.
