Yes! You can add a motor drive to your AstroMaster equatorial mount (designated CG-3 by Celestron) to easily track stars during the course of the night.
Once attached to your mount and with the mount polar aligned, the drive will accurately track objects in right ascension as they move from east to west across the sky. Only minor adjustments in declination will be needed to keep celestial objects centered in your eyepiece for long periods of time.
The drive rate can also be adjusted with a speed rate regulator that lets you follow the sun or moon with your telescope.
The current (2008) model number is #93514.
