Description
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.
I watched a couple of helpful videos on the subject so I gained a fair idea of how to collimate my telescope. In the end, with the aid of the collimation eyepiece, I was able to align the secondary mirror, which was the only one requiring adjustment.
