Flattener / Reducer / Correctors

Flattener / Reducer / Correctors

Corrective optics are a very important component, especially in astrophotography. They turn almost every refractor, Newtonian or other telescope into an astrograph. They flatten the image field, shorten the focal length or correct system-related image errors.
