To get the best images from your reflector or Schmidt-Cassegrain telescope, its optics must be in precise alignment. This economical tool will help you re-align and confirm accurate collimation for great views night after night.
The Orion Collimating Eyepiece is a combination sight tube and Cheshire eyepiece, consisting of a 5"-long tube made of black-anodized aluminum. It fits in a telescope's 1.25" focuser eyepiece holder, or in a 2" focuser equipped with a step-down 1.25" adapter. A peephole in the top and wire crosshairs at the bottom enable precise centering of reflector telescope optical components. The polished 45-degree internal surface projects a ring of light into the optical path to facilitate precise primary mirror alignment. Simply insert the Orion Collimating Eyepiece in the focuser drawtube and follow normal collimation steps.Your Newtonian reflector, Dobsonian reflector, or Schmidt-Cassegrain telescope will always be in excellent optical alignment!
