Askar 0.75x 91F Reducer (ASKAR91FR) newtonian By selectively reducing the transmissionThe 0. 75x reducer can bring Askar 91F's focal ratio down to F 5, providing not only a faster focal ratio but also built in field flattening correction. The shorter focal ratio delivers a wider field of view and a faster exposure time, making it ideal for capturing large areas of nebulae, star clusters, and faint, fast moving celestial objects. The 91F 0. 75x reducer adopts a triplet design and supports a 44mm full frame image circle. The back focus
