Farpoint Cheshire collimation eyepieces for Newtonian and Dobsonian reflector telescopes — the essential second tool in the two-tool collimation workflow trusted by experienced reflector owners. Proudly made in the USA, precision-machined, and practically indestructible.
A laser collimator gets your secondary mirror aligned and your primary into the ballpark — but a Cheshire eyepiece is what delivers the final, precise primary mirror alignment that a laser alone can't achieve. This two-tool approach is widely regarded as the gold standard for Newtonian collimation. Pair your Cheshire with a Farpoint laser, or grab one of our complete collimation kits that bundle both tools together.
Our Cheshire collimators use the same proven reflective-pane design found in the popular CATSEYE™ BlackCat series — no crosshairs, just a clean reflective surface that gives you an unobstructed view of your mirror alignment. Unlike combination Cheshire/sight tube tools that compromise on both functions, Farpoint Cheshires are single-purpose, no-compromise instruments built for precise collimation.
Each Cheshire includes a triangle center-mark template and sticker — the triangle edges touch the outside of the illuminated field, removing the guesswork of centering a traditional round center mark. Available in 1.25" and 2" sizes.
Cheshire eyepieces require no batteries, no electronics, and no calibration — they work by ambient light reflected off the precision-machined pane. They're the tool you can always count on at the eyepiece end of your scope, session after session, year after year.

Note: Farpoint Cheshire collimators are designed for Newtonian and Dobsonian reflecting telescopes only. They are not intended for refractors, catadioptric, or SCT designs.
