Moonlite Nitecrawler 2 axis Rotating Worm drive focuser wr 2,5
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 out 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.
The design of the NiteCrawler uses positioning technology currently in use in todays CNC machines. The NiteCrawler has a built in controller with display for positional information. It also provides manual Jog handles/ knobs on encoders for both focus and rotation input right at the focuser. The Jog rate of the input knobs can be selected on the controller allowing the user to pick the resolution of each click on the knob. Note the knobs have a 32 position indent feel, so each click of the knob will move the selected axis 1 unit or multiples of one unit depending on the jog rate picked.
ASCOM drivers and SKYX direct plug, or our MoonLite program can be used to operate the focuser remotely.
The NiteCrawler includes the Lower flange required to fit on the OTA it is ordered for. No need to source a 3rd party to machine a flange, we provide it free.
A universal 12 volt power supply with international plug styles is included along with a USB cable and a remote temp probe. Note if the remote temp probe is not plugged in to the controller, the focuser will use a internal temp sensor mounted on the circuit board, It is recommended to use the external remote probe for better accuracy.
One set of drawtube extender rings is included with all NiteCrawler focusers. We provide a .5", 1", and 2" thick set to allow back focus adjustment. Please note specific thread in camera adapters are sold separately. Please see NiteCrawler adapters for your imaging needs. We make an adapter for all cameras plus reducers/ flatteners.
