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.
The corrector fits to the 2" receptacle of the focuser, it corrects the image field for astrophotography
- Suitable for refractor telescopes up to 102 mm aperture or smaller (ED, apo, achromat... )
- Connection telescope side 2" barrel with filter thread
- Connection camera side M48x0.75 thread
- Working distance from M48 thread to camera sensor is 55 mm
- No shortening factor, the focal length of the refractor is not changed
