Baader Laser Collimator
!
The Baader Laser Collimator gives very accurate collimation (optical allignment) of all Newtonian and Schmidt-Cassegrain reflector telescopes, essential for getting the most out of your telescope.

Excellent value and performance at a fraction of the cost of other laser collimators.

Ultra compact, this is supplied with a keyring adapter for extra convenience.

Cheshire Collimating Eyepiece

!

The Celestron Cheshire Collimation Eyepiece is ideal for precise collimation of Newtonians and helpful for aligning Schmidt-Cassegrains. This special eyepiece fits into 31.7mm 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.

With comprehensive instructions.
