Celestron Field Flatteners, Reducers & Coma Correctors

Celestron reducers and correctors shorten the focal length of Schmidt-Cassegrain telescopes for a faster focal ratio and a wider field. The dedicated 0.7x reducer lenses for EdgeHD 800, 925, 1100 and 1400 bring each tube to about f/7 while keeping the flat, coma-free field for imaging.

The classic Celestron Reducer-Corrector (f/6.3) suits standard SCTs, reducing focal length and flattening the field for both visual and imaging use. Choose the model that matches your exact optical tube.
