MoonLite’s NiteCrawler models are a fully electronic focuser that uses fly by wire control technology for very accurate positioning in both focus and rotation. The patented design is intended for remote automation of large heavy imaging instruments providing extreme position accuracy that is repeatable down to .26 Microns.
Vertical focus motion is handled by 3 Stainless Steel rails riding on 6 large 1/2" bearings under large pre-load pressure. This allows the focuser to maintain center line mechanical point even with huge instrument loads hanging on it. Rotation is provided by an inner and outer drawtube riding on a double row bearing track providing extreme rigidity.
The drawtube is designed just like a tall bearing, but in this case is hollow. The large stainless steel lead screws provide very accurate position and no backlash up to 25 lb instrument loads. The focuser holds heavy loads even with the power off and remembers position on power up, no need to re-home each time it is turned on.
