This interface cable is designed to get the most out of the Celestron Nexstar Goto mounts.

This interface allows to connect a PC with USB port to a Nexstar hand control with RJ9 portl. In this way, the motors of the mount are controlled directly from the PC. This allows not previously possible functions: ultra-precise Goto, direct autoguiding (via ASCOM), satellite tracking, N-star alignment, synchronization, GPS support, etc ...

Compatibility: All Celestron Nexstar hand controllers with RJ9 RS232 port (not for mini USB ones)
