BIG Paracorr Type 2 3" Coma Corrector

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'.

This coma corrector was specially designed for large telescopes that have a 3" focuser. It is ideal for use with large sensors with a diagonal of up to 52 mm.
