The Flagstaff Astrometric Scanning Transit Telescope (FASTT) has been equipped with a new CCD detector, and further improvements in instrumentation have been made. An evaluation of its performance indicates that the telescope can determine accurate star positions, tied into the VLBI/VLA extragalactic reference frame, for stars as faint as V ∼ 17.5 mag. With further improvements, it is hoped this accuracy can be improved. A special scanning technique for stars at high declinations has been developed that allows scanning up to the pole. Positions tied into the extragalactic reference frame for FK5 and radio stars have been determined with the FASTT, and a comparison of these positions with their catalog values is given.
