Add right ascension (RA) tracking capabilities to Celestron AstroMaster and PowerSeeker equatorial telescopes.
This easy-to-install RA motor drive compensates for the Earth's rotation, so the telescope tracks 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, you only need to make occasional adjustments in declination (Dec) to keep an object in the eyepiece for long periods of time.
