CELESTRON COLLIMATION EYEPIECE - 1.25"

The Celestron Cheshire Collimation Eyepiece is ideal for precise collimation of Newtonians and helpful for aligning Schmidt-Cassegrains. This special eyepiece fits into 1.25" focusers or diagonals.

Alignment is easy using the small opening on one end and thin cross hairs at the other end. Note that for Newtonians faster than f/4.5, we recommend using a laser collimator such as the Baader LaserColli Mark III.
