The Sky-Watcher Coma Correct is designed for fast-ratio (f/5 optimized) Newtonian Reflectors bearing a 2" focuser.

Coma is an abberation which makes stars appear comet-like around the edge of the field. The Coma Corrector reduces this abberation to yield pin-point stars to the edge of the field, without altering the magnification.

Includes all necessary adapters for visual use. Photographic use requires a special M48 series wide T-ring (sold separately).

M48 wide T-rings for Canon, Nikon and Sony cameras can be found on our webstore.
