The Vixen MT-1 Motor Drive is a great accessory to add to your Vixen GP2, GPD2, or Great Polaris or Super Polaris series mount. This stepping motor easily attaches to GP-type mounts, and the quartz oscillator keeps the tracking true and accurate. It is able to act as either a right ascension or declination axis, but it can only control a single axis at a time-you'll need a pair of them if you want both axes to be simultaneously motorized. Constellations, however, only move in the right ascension axis over the course of the evening-so if you have your telescope well aligned to the polar axis, you really only need motorized movement on the right ascension axis.
When controlled by an SD-1 or DD-1 controller, the MT-1's accuracy is within +/-0.005% of the sidereal rate.
The optional #3828 manual clutch is needed if manual operation of either axis is to be retained.
Note: Requires axis controller.
Helps keep tracking error within 0.005° of sidereal time
