Add this motorized mount to your AstroMaster or PowerSeeker telescope (Celestron CG-2 or CG-3 mount), and you can start tracking stars. This easy-to-install motorized mount compensates for Earth's rotation, allowing the telescope to follow the movement of stars from east to west. Once the RA mount is installed and powered on, you only need to make minor adjustments, and you can track the same object for an extended period.
