About this product
Model: askar_185apo_reducer
Part Number: ASKRE18508
Askar 185 APO 0.8x Full Format Focal Reducer
The 0.8x reducer can bring the Askar 185 APO Triplet telescope's focal ratio down to f/5.6.
A shorter focal ratio allows the OTA to have a wider field of view and faster exposure times, making it suitable for capturing large areas of nebulae, star clusters, and faint, fast-moving celestial objects.
The 0.8x reducer features a quadruplet optical design that supports a 44mm full-frame image circle.
The back focus from the M48 thread is a standard 55mm. The front thread is M84*1. At the camera end, it is equipped with M68*1, M54*0.75, and M48*0.75, three sizes of adapters, which are convenient for connection. At the same time, it has a built-in M48*0.75 2-inch filter thread, which can be directly installed and used.
