Askar 0.8x Reducer for 140APO

The 0.8x reducer reduces the Askar 140 APO's focal ratio to F5.6, functioning as a standard reducer with field-flattening capabilities. This 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 0.75kg. It provides a standard 55mm back focus from the M48 thread, with an M92*1 front thread. The camera end is equipped with two adapter sizes, M54*0.75 and M48*0.75, for convenient connections.

Additionally, it includes a built-in M48*0.75 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.
