To allow tracking of celestial objects, Celestron offer an optional single axis motor drive for the CG-3 EQ Mount. Once polar aligned, the motor drive will accurately track objects in Right Ascension as they move across the sky. Only minor adjustments in Declination will be necessary to keep celestial objects centered in the eyepiece for long periods of time.
The CG-3 logic drive is powered by one 9v alkaline battery. This can power the drive for up to 40 hours, depending on motor speed settings and ambient temperature.
The logic drive is equipped with a North/South switch that can reverse the direction of the motor for Southern Hemisphere use.
The Logic motor is equipped with a speed rate regulator that allows the motor drive to track at a slightly faster or slower speed. This is useful when observing non-stellar objects like the Moon or Sun which travel at a slightly different rate than the stars.
