Although the session itself was a frustrating one (with variable transparency and seeing) the best of the images fortuitously captured the event I was hoping for: Ganymede emerging from Jupiter's umbra. This is best illustrated in the animation (rev B) ... which also illustrates the variable conditions!

Ganymede is visible as a thin crescent in the main image, along with Europa (far left) and Io (far right).

Each image is a single 2 min capture, with the best 15% of frames stacked.
