Scientific paper

An astronomical mount has been modified and upgraded to enable precision tracking of near-earth objects. A two-step process is employed: (1) ephemeris-based pointing brings the object in or near the telescope field-of-view, and (2) automatic video tracking (AVT) 'grabs' and centers the object. Tracking rates in excess of 3 deg/s in each coordinate have been achieved. When operated in the AVT mode, observed pointing errors, even at the above rates, rarely exceed 1 pixel (2 - 5 arcsec).
