Based on Moonlite's classic Crayford focuser but with their dual-speed Tri-Knob with Shaft Lock featuring an over sized 8 to 1 reduction unit with a preloaded, all ball bearing planetary reduction design that has no backlash or play. The inline unit can be rolled with the slightest touch for very fine focus movements and has an auto brake when focus is stopped. No wiggling, perfect collimation and a 6 lb load capacity make this option ideal for visual or imaging use. The fine knob is on the right by default but can be made left-handed if required.

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. 

All bearing riding surfaces polished to a near mirror-like finish before anodising for an extremely smooth focus action .

Non-marring compression-ring eyepiece clamp.  

Several colour options and drawtube lengths are available as well as matching curve adapters, spacers and install kits for a professional Installation. 

For visual use most owners select the standard 50mm draw-tube length. For imaging the shorter 38mm draw-tube is preferred. For the Skywatcher 190MN Maksutov-Newtonian please select the standard 50mm draw-tube.
