Nothing like the feeling that Jupiter is looking back at you! Almost offset that I was starting to loose feeling everywhere else. God it was a cold night to be out there, then a wind blast hits you, makes it worse and shakes the scope. Any normal Jupiter night and I'd have been back inside without a moments thought. The view was just too extraordinary though, to the left is Io (in front of the planet) just poking out. Europa (upper) and Callisto are just off to the other side. And Io is casting a shadow right on top of the great red spot. The position of the moon relative to the shadow tells you something of Jupiter's alignment to the Sun relative to our position.
