Sharpstar 0,84x Astrophoto Reducer for 50EDPH
The 0.84x reducer can bring Sharpstar 50EDPH´s focal ratio down to f/4.6. 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 0.84x reducer adopts a quadruplet design and supports an APS-C frame. The overall weight is 0.24 kg. The back focus from the M48 thread is a standard 55 mm. The front thread is M42*1 and the camera end thread is M48*0.75. At the same time, it has a built-in 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.
