Collimation Tools

Collimation is an important part of routine maintenance for Newtonian and Catadioptric telescopes. Keeping the optical axes properly aligned on all of the optical elements in your telescope produces the sharpest possible results, whether you are visually observing or doing astro-imaging.

Celestron offers an economical yet effective 1.25" Cheshire Collimation Eyepiece, which is a combination Cheshire eyepiece and sight tube, for collimation purposes.

If you are a Newtonian owner and are searching for a simple tool that can help you tweak it to perfection, then check out Celestron’s rugged and accurate 1.25" Cheshire Collimation eyepiece!

Unlike a laser collimator, this tool can help you to precisely center the secondary mirror under your focuser for the least amount of vignetting when imaging or using wide field 2” eyepieces. With such a versatile accessory at your disposal, you can finally exploit the full potential of your telescope.

The moon and planets have never looked better, thanks to Celestron’s Cheshire Collimation eyepiece!
