Askar 120APO 0.8x Full-frame Reducer

The 0.8x reducer can bring Askar 120APO's focal ratio down to F5.6. This is a standard reducer with field flattening capabilities as well. 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 adopts a triplet design and supports a 44mm full-frame image circle. The overall weight is 0.75kg. The back focus from the M48 thread is a standard 55mm. The front thread is M84*1. we have equipped three sizes of adapter， M68*1, M54*0.75, and M48*0.75 for easy subsequent connection and use. At the same time, it has a built-in M48*0.75 2-inch filter thread, which can be directly installed and used. The overall CNC machined, both end threaded metal caps prevent ash when not in use.
