Castor.

An average of 13 frames from a video taken with a SAC-IV QuickCam based CCD camera mounted on a 203.2mm f/6.3 Meade LX200 Schmidt-Cassegrain Telescope with a Meade Series 4000 x2 barlow at 10:01 PM on January 11, 2003 in New York, NY. Castor (Alpha Geminorum, 66 Geminorum, SAO60198) is a double star with magnitudes of 2.0 and 2.9 and a separation of 2.0 arc seconds. A dark frame was subtracted from each of the frames and they were aligned and averaged using Keith's Image Staker on my 600MHz iBook.
