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.

Askar Backfocus Adjuster M54(F) to M48(M) with variable 16mm-20mm extension

The M48 backfocus adjuster's front telescope interface is female thread M54x0.75 and the rear camera interface is male thread M48x0.75 (Please note that it is NOT M48 on both sides). The overall thickness is 18mm and it offers ± 2mm of adjustment range.

The backfocus adjuster is CNC machined. Each unit is a 0.05mm precision adjustment, and the surface is printed with a scale for easy adjustment and to save the position. There are two holes for fixing screws, which make the adjuster easy to use with different products.

By rotating the backfocus adjuster, it can be adjusted between ±2mm to match the backfocus requirement, and to solve the various imaging problems caused by the backfocus.
