Askar 0.8x Reducer for 120APO

The 0.8x reducer brings the Askar 120 APO's focal ratio down to F5.6. This standard reducer also has field-flattening capabilities. The shorter focal ratio allows the OTA to achieve a wider field of view and faster exposure times, making it ideal for capturing large areas of nebulae, star clusters, and faint, fast-moving celestial objects.

Featuring a triplet design, the 0.8x reducer supports a 44mm full-frame image circle and weighs 0.48kg. It offers a standard 55mm back focus from the M48 thread, with an M84x1 front thread. The camera end is equipped with three adapter sizes, M68x1, M54x0.75 and M48x0.75, for convenient connections.

Additionally, it includes a built-in M480.75 2-inch filter thread for direct installation and use. The entire unit is CNC machined, with threaded metal caps on both ends to prevent dust accumulation when not in use.
