Celestron Homepage

Any of Celestron’s mounts with an autoguider port can use a push-button (momentary contact) hand control for manual guiding of the scope.

These work by providing voltage for one or both drive directions to the mount at a rate that is slightly faster than sidereal as long as the button is pressed.

This type of control was standard equipment with Celestron mounts of the 1990s, including products like the C5+ and the Super Polaris mount.
