SV197 1.25″ Cheshire Collimating Eyepiece for Newtonian Telescopes

The SV197 Cheshire Collimating Eyepiece is a precision alignment tool designed for accurate collimation of Newtonian reflector telescopes. By ensuring correct optical alignment, it helps deliver sharper stars, improved contrast, and better overall observing performance.

The SV197 Cheshire collimating eyepiece inserts directly into standard 1.25-inch focusers or diagonals, making it compatible with a wide range of Newtonian reflector telescopes.

Compared with simple collimation caps, the Cheshire eyepiece provides clearer reference geometry, allowing more accurate mirror alignment. This results in noticeably improved star images and better high-magnification performance.

The view through a Cheshire eyepiece will vary depending on telescope focal ratio:
