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. The collimation eyepiece is more accurate than the simple Collimation Tool.
Product carries full 2 year Celestron factory limited warranty (within US/Canada only).

Celestron 1.25" Cheshire Collimating Eyepiece for Newtonian ReflePros: Cons: Comments:
Eyepiece worked fine once I figured out how to use it. The included instructions were a little vague to me, but I found some at Sky & Telescope.com.
Product arrived within the promised time-frame, and was well packaged and in excellent condition. Very happy with Agena Astro.

Bought this to collimate my ancient 8" newtonian scope and found it to be not only useful to improve viewing but also portable and requires no batteries

Great for a quick checkPros:
Simple to useCons:
Works very well for a quick check, or minor adjustment. After I set up for the night as it's still light, I will check collimation with this eyepiece and make any small adjustments. If it is off too far then I would use a Tectron set up and some more time consuming adjustments.
Have only had to do that once so this eyepiece keeps the optics in line longer for me. I just keep it in my eyecase and ready to goSort by
