JMI - MOTOFOCUS for Meade ETX Telescopes



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:

  • Meade - ETX-90 (non-EC version), ETX-90EC, ETX-90PE, ETX-105EC, ETX-105PE, ETX-125EC, ETX-125PE


MOTOFOCUS is especially important for the ETX when viewing near Zenith (in Alt-Az mode) because it is very hard to reach the focus knob at this position.  We use miniature motors (motor and gear box size is 1" x 0.5" x 0.375"!) for a very small package.


The hand unit cord is plugged into the side of the miniature motor assembly.


The MOTOFOCUS hardware does not interfere with vertical operation at Zenith
