JMI - Model NGFXTNM Crayford Focuser with Motor (Newtonian scopes)
For the ultimate focusing system adding this motor upgrades a manual NGF focuser to a motorized focuser. It includes the motor and any necessary mounting hardware as well as a hand control unit. The motorized system will lift up to 12lbs.
The Next Generation Focuser (NGF) is a low-profile, friction-drive focuser designed for both the amateur and professional . The highly acclaimed Crayford design permits tolerances up to 100 times better than conventional rack-and-pinion focusers. Zero image shift and zero backlash makes it fantastic for visual and photographic work and a must for CCD imaging.
This Newtonian version includes a removable combination base (works on 10" radius up to a flat surface).
The NGF 3" focusers include a compression ring in the drawtube for holding eyepieces and accessories without scratching the equipment. The adjusting screw presses against the ring which tightens around the eyepiece or accessory.
