JMI - MOTOFOCUS for Orion Single-speed Crayford Focuser


JMI MOTOFOCUS for Orion Crayford Focuser with Single-speed Knobs



MOTOFOCUS is a battery operated hand control with an electric focus motor that attaches to the shaft of a focuser knob (or the knob itself) for precise, vibration-free focusing without the need to touch the telescope.  It is great for visual and photographic use and features variable speed for coarse and fine adjustments.  Precise positioning is accomplished through electronic braking.  Mounting is easy and requires no drilling or tapping.  Add the optional Digital Read Out (DRO), or Digital Focus Counter (DFC), for improved focusing accuracy and repeatability.


Compatible models:

  • Orion: ED80 / ED100 Apo Refractors, SkyQuest XT8 / XT10 / XT12 (with Crayford focuser), SkyView Pro 8 EQ / 80 EQ / 100 EQ



The Orion 80mm and 100mm ED Apochromatic Refractors use a Crayford focuser.  Our MOTOFOCUS unit designed for the Orion Crayford focuser, includes a mounting bracket, miniature motor, two gears, hand unit (not shown) and power cord (not shown).  The motor can be easily disengaged for manual focusing.  This model will not work on the Dual Speed version.
