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.
TS Photoline 0.8x Focal Reducer and Corrector for Refractors up to 102 mm Aperture
The corrector increases the speed of your refractor telescope and reduces the focal length for a larger field.
