CCD and video astrophotography Imaging with a large aperture reflector like the Obsession is exciting. The large light gathering area means CCD exposure times are very short - usually under a minute. Minimal guiding or none at all. Multiple images are stacked in your PC to build up a vivid image. With proper software, field rotation at the focuser is elliminated. Live video work is the ultimate in immediate gratification. The newer cameras are very sensitive. Entertain a crowd with deep sky images on the monitor. Actually see deeper than you can with eye at the eyepiece in real time! Or connect to a DVD camcorder or VCR and capture the video to watch later. Or make stills of the best shots.
