Dial-in detailed views from your Schmidt-Cassegrain telescope with this dual-speed 2" Crayford focuser. Its fine-focus control knob lets you adjust focus at an 11:1 ratio compared to the coarse adjustment knobs for exceptionally precise focus control. The Crayford design makes this SCT focuser free of backlash for smooth performance.

With this external Crayford focuser installed, troublesome image shift caused by the standard, internal Schmidt-Cassegrain focus mechanism is eliminated since the telescope's primary mirror can be locked in-place. Additionally, the Orion 2" Dual-Speed Crayford Schmidt-Cassegrain Focuser provides much smoother and more precise focus adjustment control compared to the standard internal focus mechanism. The focuser's threaded collar is compatible with Celestron and Meade brand Schmidt-Cassegrain telescopes. 

The focuser drawtube allows 30mm of travel and features an engraved millimeter scale for easy referencing and focus-position repeatability. Its rotatable housing lets you position the focus knobs just the way you like. 

This 2" Crayford focuser accepts 2" diagonals, eyepieces, and astrophotography accessories. An included step-down 1.25" adapter makes the focuser compatible with 1.25" astronomy equipment also. Both the 2" and 1.25" holder feature compression rings that won?t scratch inserted eyepieces, camera nosepieces, or other accessories when tightened.

Weighs 2 lbs., 4.7 oz. including the step-down adapter.
