Optical telescopes and cameras are often used to determine the initial pointing model for radio antennas. After this initial determination, the optical systems are typically not used. The Combined Array for Research in Millimeter-wave Astronomy (CARMA) has implemented optical oset pointing as a standard calibration option for science observations. We report on the proof of concept testing, the method, and the typical improvements obtained over traditional radio pointing. We conclude with a brief discussion of future directions, which may oer further improved pointing at CARMA and at other facilities that require increased pointing accuracy.
