Yes, I also spent most of the evening observing this event with my G9.25.
Even better I got a sequence of images over a three hour period, including
the occultation of Callisto behind Jupiters limb, using a webcam (Philips
Toucam). As soon as I have the image sequence processed (which is rather time
consuming I'm afraid) I'll upload them to my webpage for everyone to see.
Best wishes & clear skies,
