Orion 13039 2-Inch Crayford-Style Telescope Focuser

Upgrade your Orion reflector with a quality 2 Crayford-style focuser. Designed to replace 2 rack-and-pinion focusers on Orion telescopes, the Crayford-style focuser provides an unmatched level of focusing smoothness and precision. This deluxe cast-aluminum focuser provides super-smooth roller bearing motion, zero image shift, machined metal knobs, and a tension adjustment control. It has a racked-in height of 2-11/16 and 1.4 (35mm) of drawtube travel. Its internally blackened for greater contrast. Accepts 2 and 1.25 eyepieces. The 2 Crayford focuser has the identical mounting hole pattern and spacing as the 2 rack-and-pinion focuser on older Orion 8- to 12 Dobsonians (except the XT8 Classic) and other 8 and 10 reflector tubes, so no new holes have to be drilled. NOTE: For 203mm (8) f/4.9 and 254mm (10) f/4.7 Orion reflectors, a #5122 adapter is needed to reach focus. T-thread camera adapter (#5117) sold separately.
