This is just under a 4 hour star trail taken at the 2005
Okie-Tex Star Party. A star trail is taken from a fixed tripod.
If done digitally, one or more frames are exposed and then later combined to show the relative
motion of stars across the sky over the duration of the shot. In this
case, the motion of the star party guests carrying red light flashlights on
the east observing field is also captured. This shot is looking to the
southwest into Sagittarius and the heart of our galaxy. The hazy cloud
appearance in the sky is the Milky Way. The West Ridge at Camp Billy
Joe provides the horizon with the camp's main building and dining tent in
the distance below the ridge.
