120 Inch Telescope Right Ascension and Declination Slow Motion Drives

The first Boller and Chivens project involving telescopes was the Right Ascension and Declination slow motion drives for the 120 Inch Telescope at Lick Observatory at Mount Hamilton, California.Phantom Telescope Dome Computer transmits telescope’s Right Ascension and Declination position to automatically align the dome’s azimuth rotational positions and the dome slits vertical opening size.
