Rigel Systems nFOCUS Motors and Controller
Motorize your Guan Sheng Crayford, or Stellarvue / Williams Optics single
speed Crayford focuser with the Rigel nFOCUS motor and controller and
enjoy ultra precise focusing with zero scope wiggle!
The motor unit replaces the left side focuser knob using existing screw
holes and supplied hardware. The nFOCUS controller connects to the
motor unit with a 30" cable, and fits in the palm of your hand. Advanced
logic control and pulse width modulation allows precise control in two
directions and at two speeds with only two buttons. Two control knobs
also allow continuous adjustment of the motor speeds from extremely
slow to fast. It's amazing to see nFOCUS work, focus changing step by
step until it's just right. No more coasting past then back past then back
The focus knob can not be operated manually with the focuser coupled,
but a thumbscrew allows the motor gear to be easily removed, restoring
manual operation without dismounting the motor. Operates on 3 AA
batteries (supplied) for long life. With installation and operating
instructions, 5 year manufacturers warranty. Priority shipping included.
The Rigel Systems nFOCUS Motor and Controller are also available
installed on GSO Crayford focusers for Newtonians, Dobs, XT-I Dobs,
refractors and SCTs. Focusers come with 1.25" compression ring adapters.

#RNFC is the Rigel Systems nFOCUS Controller only, for use with other
motorized focusers like Moonlite, Van Slyke, JMI, Celestron and MEADE
