Saturn about ready to pass in front of M1, the crab nebula. At the time of this image Saturn is about 4 arcminutes east of the center of M1. The anglular size of Saturn (20 arcseconds) is about 15 times smaller than M1. However, Saturn is so much brighter than M1 (mag 0.4 vs. 8.4), that it is completely over exposed in these one minute exposures. The image above shows saturn at the same image scale, with an exposure time of 0.02 seconds.
