The Celestron Cheshire Collimation Eyepiece is ideal for precise collimation of Newtonians and helpful for aligning Schmidt-Cassegrains. This special eyepiece fits into 1¼" focusers or diagonals.

Alignment is easy using the small opening on one end and thin cross hairs at the other end. The collimation eyepiece is more accurate than the simple Collimation Tool.

Unfortunately our dealer agreements with Meade, Coronado, Celestron and Orion only permits us to ship their telescopes and accessories to addresses inside the United States of America.
