I was out the last couple nights too. It's been fun. I shot Jupiter as you guys were watching and Io did indeed pass in front of Jupiter, shadow and all (with the GRS trailing too). Here's the shot I took:
Tonight was even better. I took a lot of shots but I haven't processed any except for this one:
The shadow transit tonight was from Europa. I lost Europa itself before this shot, but for a while I was tracking it in front of Jupiter and could see it quite clearly. The moon on the left is Io and the moon on the right is Ganymede. The atmoshere was more stable and I collimated my scope through the camera, which I think helped.
I also saw nine meteors, two of the Perseids. Both Perseids were better than the others, but the second Perseid I saw was a very nice, long, but fast one with a lingering trail. They seems to be radiating from closer to Cassiopeia than what Starry Night says they do.
Well, time to hit the sack. It was AGNFA!
