This simple Right Ascension (RA) motor drive allows your Celestron AstroMaster or PowerSeeker equatorial telescope, or any set-up that uses a Celestron CG-2 or CG-3 equatorial mount, to compensate for the Earth’s rotation, so that the telescope will track a star's movement (or nebula, galaxy etc) through the night sky from east to west. When the telescope mount is properly polar aligned and the RA drive is attached and operational, only occasional adjustments in declination (Dec) is needed to keep a celestial object in the eyepiece for long periods.
The Celestron single-axis motor drive runs on a single 9V battery, so there are no cords to get in the way or snag on your mount. The drive can be used in either the Northern or Southern Hemisphere by simply flipping the North/South (N/S) switch on the face of the motor drive casing. Solar System objects like the Sun, Moon and comets, move through the sky at different rates than stars and deep-sky objects do, so to account for this a “Speed Rate Regulator” knob, which is located just under the power indicator, can be turned in either direction to slow down or speed up the motor drive.
