Thanksgiving Family Star Party

This Thanksgiving holiday, we went back to visit family in Las Cruces, NM.  While there, I setup an impromptu star party in my father's backyard.   The city street lights did not make for great deep-sky observation but we all had a peek at a few interesting objects including Jupiter and Orion.

While observing Jupiter, I noticed that a moon shadow was transiting the surface.  After everyone had seen it visually, I plugged in a webcam and was able to get a nice sequence of not only the moon shadow but also the moon itself passing beyond the limb of Jupiter.  Later looked it up to determine it was Io.
