The 0.8x reducer for the ASKAR 140APO is a dedicated corrector which transforms the telescope into a 784mm f/5.6 astrograph with a 44mm image circle. The working distance between the reducer and the sensor is 55mm from the M48 x 0.75 thread.

The reducer can be connected to the focuser of the Askar 140APO using an M92 x 1 male thread. On the camera side there are M54 x 0.75 and M48 x 0.75 male threads. The flattener has an internal M48 x 0.75 thread to accept any standard 2" filter.
