Video segments (four) on the Keck Telescope
Four video segments are described in accompanying memo from E. C. Stone dated January 3, 1991. 1. Computer-aided design sequence showing buildup of the telescope, starting wit the segmented mirror and ending with a simulation of the azimuth and elevation motions (0:00-3:25); 2. Time-lapse sequence showing segment being lowered into telescope, followed by a very rapid azimuth motion and a more leisurely elevation motion (3:30-5:40); 3. Sequence of views of the nine segments in the telescope, ending with camera looking directly at the star stacking camera at prime focus (5:18-5:40); 4. Star stacking sequence with nine separate images dispersed into three groups. [more follows]
