Cheshire Collimator for 1 1/4" Eyepiece Reflector Telescope laser engraved 20oz tumbler but only hold in oneThis Cheshire collimator is designed for a reflector telescope that incorporates a standard 1 1 4" focuser and eyepieces. This scope accessory offers "one piece" construction, allowing quick and precise alignment of the primary and secondary mirrors of the reflector. Our unique cross hair center hole makes perfectly centering the lens dot much easier. A distance of 5" from peephole to cross hairs gives a much better sight radius than most collimators,
