Due to high demand and global product shortages due to the pandemic, please call for availability.

The Sky-Watcher f/4 Coma Corrector is designed for fast-ratio (f/4 optimized) Newtonian Reflectors bearing a 2" focuser, such as the Sky-Watcher Quattro series.

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.

Requires a special M48 series wide T-ring (sold separately).

Please note: standard T-rings will not mate. If you're not sure what you have, please contact us; we'd be happy to assist you.

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