JMI Telescopes Dual-Control Hand Unit

The JMI Telescopes Dual-Control Hand Unit allows simultaneous control of a JMI MOTOFOCUS focus motor and a MOTODEC declination axis motor.  On top of the unit are two 1/8" (3.5mm) miniphone ports-a standard miniphone cord connects this hand unit to the focusing and declination axis motors.

It has forward and reverse buttons and two toggle switches-one to select whether it is actively controlling the focusing or declination axis, and another three-position switch (off/a/b) for slow-speed control (handy for high-magnification).
