Celestron Telescopes Collimation Specialty Eyepiece 1-1/4" 94182 ,

The Celestron Newtonian reflector collimating tool 94182 is a combination of a sight tube and a Cheshire tool in a single unit. It has the precisely centered sighting hole and crosshairs of a sight tube, plus the cutout in the side of the tube containing the very precise 45° angle reflecting surface of a Cheshire tool. As it is a combination tool, it is less expensive than buying a separate sight tube and Cheshire tool.

Celestron Cheshire Collimation Eyepiece is ideal for precise collimation of Newtonians and helpful for aligning Schmidt-Cassegrains. This special eyepiece fits into 1 1/4" focusers or diagonals. Alignment is easy using the small opening on one end and thin cross hairs at the other end. Specialty Collimation Eyepiece is more accurate than the simple Collimation Tool.
