Cheshire Collimators

The essential second tool — delivering the final, precise primary mirror alignment a laser alone can't achieve.

A laser collimator gets your secondary aligned and primary into the ballpark; a Farpoint Cheshire eyepiece completes the job. Our Cheshires use the same proven reflective-pane design found in the popular CATSEYE™ BlackCat series — no crosshairs, just a clean reflective surface for an unobstructed view of your mirror alignment. CATSEYE™ is a trademark of CatEye Collimation; Farpoint is not affiliated with CatEye Collimation.

Each Cheshire includes a triangle center-mark template and sticker and requires no batteries, electronics, or calibration. Available in 1.25" and 2" sizes, precision-machined and practically indestructible. Designed for Newtonian and Dobsonian reflecting telescopes only — not intended for refractors, catadioptric, or SCT designs.
