Add right ascension (RA) tracking capabilities to any Celestron AstroMaster or PowerSeeker equatorial telescope, or any setup that uses a Celestron CG-2 or CG-3 equatorial mount. This easy-to-install RA motor drive compensates for the Earth’s rotation, allowing the telescope to track a star’s movement through the night sky from east to west. When the telescope mount is properly polar aligned and the RA drive is attached and running, the user only needs to make occasional adjustments in declination (Dec) to keep an object in the eyepiece for long periods.

The Celestron single-axis motor drive runs on a 9V battery, eliminating cords that could get in the way. The drive can be used in either the Northern or Southern Hemisphere. To change hemispheres (reverse the motor’s direction), simply flip the North/South (N/S) switch on the face of the motor drive. It is also easy to change the speed of the motor. A speed rate regulator knob is located just under the power indicator and can be turned in either direction to slow down or speed up the motor. Since solar system objects like the Sun and Moon move through the sky at different rates than deep-sky objects, this feature allows you to match the motor’s speed to the particular type of object you are observing.
