This is one of my first shadow transits of the moon Callisto, they don't happen as often as some of the other moons, and it is very interesting to photograph. And since Jupiter's opposition is coming up it looks very big in my 8'inch telescope even with a 25mm eyepiece. And to make it more interesting, the time that I was observing the great red spot was visible.
