Another Jupiter Photo

The skies in the city were much clearer tonight, so I took more shots of Jupiter. I've included one of the better ones below. I tried a range of exposures from 1 sec. (way too long) to 1/50th sec. (moons too faint... could barely see two) and found anywhere from 1/5th to 1/10th sec. to be about right. In no cases could I resolve the darker bands in the atmosphere. The inner moon is Io, which had just completed a transit of Jupiter a little over three hours earlier than this photo. The next two out are Europa and Ganymeade (very close together with Europa just inside and slightly above) and the outer moon is Callisto. I'm going to try to get a shot at higher elevation in darker and clearer skies on Wednesday and should post it Wednesday.
