Dual Shadow Transits on Jupiter

Friday morning, August 13, 2010, the shadows of Ganymede and Io were falling on the disk of Jupiter during the morning twilight. From the calculations of Curt Renz, I knew that Io's shadow would appear at 5:09 AM Chicago time. I wanted to view this, and if I could, to get images. I have had a cheap Meade Lunar & Planetary CCD imaging system for awhile now, but have not used it much. I brought it for the Perseid peak to try to capture the dual shadow transits on Jupiter Friday morning. The results are not great, but over the course of nearly four hours I recorded the motions of the Galilean Satellites.
