Vixen's MT -1 Motor can be used as either a right ascension or declination motor. The MT-1 Motor is controlled and powered by an optional Vixen SD-1 single axis or DD-1 dual axis drive controller. One MT-1 motor is needed for the single axis right ascension operation or two motors are required for dual-axis operation. When controlled by an SD-1 or DD-1, the accuracy of the MT-1 Motor is within +/-0.005% of the sidereal rate. The optional Item 3828 Manual Clutch, described below, is needed if manual operation of either axis is to be retained.
