Product description

Optimized for the super-fast Skywatcher F4 Newtonian telescope, this coma corrector ensures pinpoint stars right out to the edge of your exposure. It does not change the focal length. The back focus is 55mm.

A coma corrector is a corrective lens for Newtonian telescopes. This type of telescope can cause distortion of the image at the edge of the field of view, making stars look like little comets. This aberration is therefore called 'coma'.

Customer reviews

A really good CC

Review by E. S. on 12.03.2024 08:42:26

( 5 / 5 )

A very good CC that holds its own against the more expensive brands. Pretty tolerant to tilt, and does not fuzzy up the stars.
I'm using it with SW Quattro 8 and Canon 6D Full frame. IT does not cover the very edges of the image, but I am very happy with this CC where it covers the image. I plan to buy aps-c camera in the future so the CC should cover it.

The image height is 28mm
