Rigel Systems nFOCUS DC Focus Motor Kits
nFOCUS motor controller provides the ultimate in accurate focusing. nFOCUS is the affordable way to get high precision fine focusing without vibration for visual and astro-imaging! nFOCUS motor controller provides the ultimate in accurate focusing. nFOCUS is the affordable way to get high precision fine focusing without vibration for visual and astro-imaging!
Low speed is adjustable pulse width modulated (PWM) drive, providing full voltage torque for reliable low speed operation on every button press. Press a second button down while holding the first button down and nFOCUS digital logic control switches to high speed drive, to get you to focus quickly.
nFOCUS avoids the problems with the focus motor controllers which adjust voltage to adjust speed and thereby don't have the umph to even turn the motor over at low speed. The nFOCUS whacks the motor with a full 12 volt, short duration pulse to overcome stiction at low speed operation, providing plenty of umph!
It is amazing to see nFOCUS work, to see the focus change step by step till it's just right. No more coasting past then back past then past focus again. Uses 3 AA batteries (included) for long life. Compatible withJMI, Celestron, MEADE LX200GPS microfocuser, Moonlite DC focus motors.

For this product, see : Rigel Systems USB-nFOCUS Adapter (NF-USB)
USB-nFOCUS adapter connects your nFOCUS to your PC for easy remote operation of your focuser. ;All the great features of nFOCUS (see above) now available from your computer! Fully ASCOM; compliant so it will work with popular focus control programs. Full step size and interval control from computer and display of step count. Computer control , doesn't affect manual operation (doesn't change your favorite nFOCUS manual pulse width/interval settings).
USB and nFOCUS cables included. Software drivers for Windows xp/vista/7/8/9/10/11. Full step control from computer and display of step count, Supports relative focusing, forward and reverse direction. Store five positions for major changes in focus (e.g., camera1 to camera2 to eyepiece type '1' to eyepiece type '2'). Just focus once and save the position and a label for later 'GoTo' .
nFOCUS Temperature Sensor
For this product, see : Rigel Systems nFOCUS Temperature Sensor (NF-TS)
Telescopes change focus as temperature changes expand/contract the length of the telescope tube as temperature increases/decreases. Adding the external temperature sensor to the usb-nFOCUS adapter allows your autofocus software to and automatically compensate for these temperature changes. Unlike internal temperature sensors located inside the controller that are affected by the heat generated by the electronics, the external temperature sensor can be attached to the telescope to get a more accurate measurement of the ambient temperature.
