I took 40 x 120-second avi’s (using a Philips webcam attached to my telescope) over about 2 hours, stacked and processed them to produce 40 images and then put those images together to create this animation.
Apologies for the poor quality, but seeing was variable over the session. Also, I had to reset my tracking platform 3 times during that period which tilted the planet on the webcam. I thought I had rotated the images enough in Photoshop, but a few of them seem to have slipped through.
The animation starts with the GRS and an Io shadow transit, as well as Io itself. The new impact scar also puts in an appearance. If you watch after Io’s shadow disappears off Jupiter, you’ll see Io itself appear on the limb and it looks like it gets hurled off into space! It’s quite funny to watch.
Hope you enjoy.
