JMI MotoFocus+ Meade ETX
Focusing is made easy with JMI MotoFocus – Meade ETX. 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 at high power without the need to touch the telescope.
MotoFocus 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.
Compatible with 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.
NOTE: Meade modified their ETX scopes near the beginning of 2014. The newer versions will not work with our current MotoFocus unit. You can identify the new ETX version by the emblem on the side of the fork (see photo).
