Abstract

A parallax program using a Charge Coupled Device (CCD) at the prime focus of the KPNO 4-m telescope has been underway since July 1980. The goal of the program is the determination of the distances to a sample of intrinsically faint normal and degenerate main-sequence stars. Program stars were selected on the basis of their large proper motions, extremely red colors, and faint apparent magnitudes. The CCD appears to be an excellent astrometric detector. Preliminary analysis of several standard fields indicates that image centers accurate to better than 0.25 micron (5 milli-arcseconds) can be obtained from 120 second integrations.
