Now Includes Shaft-lock!
This is a premium quality direct-replacement thread-on focuser for smaller SCTs that have the standard 2" threaded back such as the Meade 8" and the Celestron 8" and 9 1/4". It simply threads on the rear visual back then is rotated to the desired orientation and locked in place if required.
Moonlite's silky-smooth dual rate tri-knob focuser with Shaft-lock features a fine-focus 8 to 1 reduction system using an inline all ball-bearing planetary designed unit.
The .90" travel Crayford design provides the zero backlash and no image shift performance necessary for perfect collimation. Highly polished hard anodised bearing riding surfaces for an extremely smooth focus action and a 6 lb load capacity.
The Shaft Lock mechanism is a unique mini brass compression ring clamp that allows the user to lock the shaft without deflecting the drawtube. This type of focus lock is much better then the old 'thumb screw against the draw tube' style that shifts the image when clamped.
Non marring compression rings both on 2” drawtube nosepiece and 1.25” eyepiece adapter.
The ultimate upgrade for your SCT!
