The Sky-Watcher is a dual-purpose tool that can be used for astrophotography and other imaging applications. It features a field flattener and a 0.85x focal reducer. These components correct the spherical aberrations in curved lenses, which can lead to distorted images. The Sky-Watcher's focal reducer reduces the scope's focal ratio to create a wider field of view. This enables you to take more pictures in the same time without compromising on performance. The Sky-Watcher's focal reducer also reduces the f/ratio of the optical tube to 4.93 from its native f/5.8. This allows you to take more pictures in the same time without compromising on performance. It features a reduced exposure time of 38% and a 55mm back focus distance. Reduce spherical aberrations in the entire field of view to create flat images without the appearance of streaking or curvature at the edges. It's compatible with both full-frame and APS-C cameras, although smaller and APS-C crop sensors are recommended.
