Jupiter time lapse from September 5. The video starts off with Moon Ganymede at the top left, and Io in the middle of the planet (Hard to see at first, but watch it a few times). As the planet rotates, Io creates a shadow transit that follows it across. At the same time, Ganymede crosses the planet's surface, but the angles are not right at this time to make a shadow transit. Toward the end of the video, Callisto can be seen moving from right to left. As it is about to pass behind Jupiter, the video ends. I would have gone longer, but clouds and seeing. Plus I was cold out there. :P There is a little jitter in the middle where I had to do a meridian flip. Seeing was good to average (with occasional cloud) during the sequence.
Each frame of this 57 frame sequence was a stack of 3 minute AVI's, with 30 second gaps between.
Taken with a deforked Meade LX90 ACF 8" F10 SCT at a bit longer than prime focus with an Svbony SV305 one shot colour camera, on an NEQ6 with belt and zero backlash upgrades. Captured in sharpcap, gain was set to 2.5, 42ms exposure, stacked in AS!3, levels and unsharp mask in Photoshop and the GIF made with PIPP.
