Cheshire Eyepiece · 1.25"
The critical second step — final, precise primary mirror alignment a laser alone can't deliver.
The Farpoint 1.25" Cheshire Collimation Eyepiece is the essential second tool in the two-tool collimation workflow for Newtonian and Dobsonian reflectors using standard 1.25" focusers. Our Cheshire uses 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, the Farpoint Cheshire is a single-purpose, no-compromise instrument. Precision-machined and red anodized, practically indestructible, and requires no batteries. Made in the USA.

In the box
Farpoint 1.25" Cheshire collimation eyepiece (precision-machined, red anodized aluminum), plus a mirror center-marking template and triangle center spots — the triangle edges touch the outside of the illuminated field, removing the guesswork of centering a traditional round dot (standard template works with mirrors up to 12.5")
For
Newtonian and Dobsonian reflectors only — not for refractors, catadioptric, or SCT designs
Where it fits in the workflow
Laser→Cheshire (this tool)→Autocollimator
A laser gets your secondary mirror aligned and your primary into the ballpark — but the Cheshire delivers the final, precise primary mirror alignment that a laser alone can't achieve. An autocollimator can refine it further.

Complete the two-tool workflow. Pair this Cheshire with a Farpoint 1.25" laser collimator, or save with our 1.25" Collimation Kit (laser + this Cheshire + center-marking kit + carrying case). Need a 2" Cheshire instead? See our 2" model. Need even more precision? Our 2" Super Kit adds an autocollimator for iterative refinement.
Frequently Asked Questions
Will this Cheshire work on my SCT or refractor?
No. The Farpoint Cheshire is designed for Newtonian and Dobsonian reflecting telescopes only. It is not intended for refractors, catadioptric, or SCT designs.
Does it have crosshairs, and does it need a battery?
No to both. The Farpoint Cheshire uses a reflective-pane design with no crosshairs, giving you a clean, unobstructed view of your mirror alignment. It is lit by ambient or daylight and requires no batteries.
How is this different from a combination Cheshire/sight tube?
It uses the same proven reflective-pane design found in the popular CATSEYE™ BlackCat series. Unlike combination Cheshire/sight tube tools that compromise on both functions, the Farpoint Cheshire is a single-purpose, no-compromise instrument built for precise collimation. CATSEYE™ is a trademark of CatEye Collimation; Farpoint is not affiliated with CatEye Collimation.
Do I still need a laser if I have this Cheshire?
For best results, yes. A laser gets your secondary aligned and your primary into the ballpark, while the Cheshire delivers the final, precise primary mirror alignment a laser alone can't achieve. This two-tool approach is widely regarded as the gold standard for Newtonian collimation.
