Askar 0.8x Full-frame Reducer Professional Astronomical Accessory for 103APO Telescope

Askar 0.8x Full-frame Reducer Professional Astronomical Accessory for 103APO Telescope

Description:
- The 0.8x reducer can bring 103APO's focal ratio down to F5.4. 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 shooting 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 0.48kg. The back focus from the M48 thread is a standard 55mm. At the camera end, it is equipped with M54x0.75 and M48x0.75 two sizes of adapters, which are convenient for connection. At the same time, it has a built-in M48x0.75 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.
