Hi all

Here's an 8-frame animation of Jupiter, including 5-frames showing her moons Europa, Io and Callisto in motion.

Jupiter's Moons in Motion (1mb animated gif) Remember to scroll to the right!

Callisto, moving towards Jupiter, is casting the shadow on Jupiter in the first few frames.
Europa and Io are in a close pairing, moving away from Jupiter.

I was lucky enough that Callisto was *just* close enough to Jupiter so that I could capture a reference frame to pinpoint the Moon's position relative to Jupiter. I could then capture a separate set of avi's with the 3 moons in the same Field of View. This was repeated 5 times throughout the session to get the data for the animation.

Jupiter's 8-frame animation was tricky to align in terms of limbs and colour balance, because the first 4 frames were captured in poorer seeing at 30fps with a decreasing histogram due to the mirrors fogging up. The last 4 frames were captured at 15fps with a much fuller histogram in improved seeing.

Attached is a single frame from the animation - you need to click on the link below to see the full animation.
