MicroTouch Autofocuser - Wired

PRICE: 499.00

MicroTouch Autofocuser - Wired Description

The MicroTouch Autofocuser is designed to work with the popular Feathertouch line of focusers from Starlight Instruments. The MicroTouch allows autofocusing of a CCD camera when interfaced with a computer (via USB). Included features also include Temperature Compensation, Digital Readout, and Manual Operation. The MicroTouch works with both regular Feathertouch (Crayford-style or rack-and-pinion) focusers and the Feathertouch SCT MicroFocusers.


  • Automatic focus with ASCOM-compatible software (FocusMax, MaxIm DL, ImagesPlus, etc)*
  • Temperature compensation using built-in thermistor
  • All electronics in single hand-controller box -- no separate hub and extra cables
  • Manual control with hand-controller box for use visually or with video cameras/webcams
  • MicroTouch software for configuring system and remote manual operation

* Note: Autofocusing with FocusMax requires MaxIm DL or CCDSoft for camera control interface.

FocusMax Star List for HyperStar
Download this handy list of 24 perfect stars for focusing with FocusMax, the MicroTouch, and a HyperStar. Because of the sensitivity of HyperStar, the usual 3rd to 4th magnitude stars for training First Light in FocusMax are too bright. This list gives 5th to 6th magnitude stars, ideally located for northern hemisphere observers in the evening sky each month. Just type in the RA and DEC into your goto scope and you'll easily find the perfect focusing star!
