Your telescope shows blurry stars when mirrors fall out of line. This collimator lets you fix that fast. You look through the eyepiece, spot the mirrors inside, and adjust them until they line up perfectly.

The Cheshire collimator sits in your scope just like a regular eyepiece. You dial in your primary and secondary mirrors without needing extra equipment. It works on any Newtonian telescope you own. Online guides walk you through the steps so you get great results the first time.
