1.25" Cheshire Collimator with Cross Hair Sight Tube
for Newts and Dobs
The Cheshire Collimator is the standard tool for collimating
Newtonian and Dobsonian telescopes. Even when a laser
collimator is used, the Cheshire is used for finer alignment.
Made of black anodized aluminum, with crosshairs and
removable peephole insert with angled reflective surface.
Mounts in a 1.25" focuser or 2" focuser with adapter.
Prices include shipping in the USA!
A great guide to Newtonian collimation
