Orion Telescope Collimation Eyepiece


Precise optical alignment is necessary in order to obtain the best images from your reflector telescope. To this end, the affordable Orion Telescope Collimation tool will aid with realignment and confirm accurate collimation for consistently great views.

This collimation tool combines a sight tube and Cheshire eyepiece, with a black-anodized aluminum tube 5" in length. Compatible with 1.25" telescope focusers, or with 2" focusers using a 1.25" step-down adapter. Contains an upper peephole with wire crosshairs at the bottom for accurate centering of Newtonian reflector telescope optical components. A polished 45º degree internal surface extends a ring of light into the optical path to enable precise primary mirror alignment. Directly insert the Orion Collimating Eyepiece into the focuser drawtube and observe regular collimation procedure. This will assure the best possible optical alignment for your Newtonian telescope. Includes instructions.
