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 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.

5.0 out of 5 stars Quick Collimation for Newtonians, March 9, 2007

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.

5.0 out of 5 stars Bad collimation is a scope killer!, August 8, 2008

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 will collimate most Newtonians with minimal effort. No laser beam is necessary. Follow the instructions.
