Product Description
The Celestron Cheshire Collimation Eyepiece is ideal for precise collimation of Newtonians and helpful for aligning Schmidt-Cassegrains. This special eyepiece fits into 1ΒΌ" 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.

Bad collimation is a scope killer!

This thing works. Right out of the box I was able to line up my mirrors in less that an hour to textbook perfect diffraction rings on a star. It is the first real collimation my scope has had since I got it.
I bought a cheap Dobsonian over twenty years ago. Didn't use it much, had a couple of cheap eyepieces. It made pretty good images compared to other scopes but I was never sure of the collimation.
Fast forward to today when the internet allows people to communicate with each other! Read the reviews on collimators and the articles on collimation. This device is a consistent favorite. Cheap and effective, it goes right to the front of my new and improved eyepiece collection.
This is a must have for a reflector.

I have one of these and I love it! It allows me to get my mirror alignment perfect. You don't have to worry about the Laser being off or any problems like that. This will allow you to get your collimation exactly dead on for the best image possible. Plus you don't have to worry about battery's running down.

This thing is great. Very useful in collimating your Dobsonian. Use this first, then fine tune with a laster collimator.
Great device!

This will collimate most Newtonians with minimal effort. No laser beam is necessary. Follow the instructions.
Quick Collimation for Newtonians
2007-03-09
Celestron's tool is easy to carry, easy to use, and (at least in my case!) gives me quick, precision collimation with my Newtonian. Why pay for a laser collimator (which needs to be calibrated) when you can use this?
Collimation is the most important part of your setup; without good mirror alignment, all you'll see are blobs and blurs even on the best viewing nights. This combination tool makes aligning both primary and secondary mirrors fairly painless, and also fairly fast. Highly recommended for any level of observer.
