Watching Jupiter set seemed to be a major theme of this past summer's vacation. ;-)
Another shot from a very cold and clear night at Newberry National Volcanic Monument in Oregon. That's Jupiter just about to set over East Lake. Consider for a moment how that little blip is 2.5 times more massive than all the other planets in our Solar System combined.
Technical info: Thanks to Mtnguyd for pointing out the EXIF data seems to be partially stripped. The specs were: 30 sec, F4, 17 mm at 800 ISO.
