Askar 0.75x 91F Reducer (ASKAR91FR) newtonian Minimal vibration for steady long-exposure

Minimal vibration for steady long-exposure photography

virtually eliminating periodic error and solidifying the status of the EQ8-Rh as an imminently precise

The result is that both the ALP-T dual band 5nm Ha&OIII and SII&Hb filter creates a superior signal-to-noise ratio and better contrast in your OSC images

even when tested with f/4 scopes

Askar 0.75x 91F Reducer (ASKAR91FR) newtonian Minimal vibration for steady long-exposureThe 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
