I set up the camera by the Chess Queen formation at Coyote Buttes South for this sequence. I used the 50mm lens wide open at f/1.8. I left it there all night. It ran until the battery gave out. The camera was facing toward the east.

There are a few strange features. I wouldn't have guessed that there were so many airline flights overhead. Also, at about six seconds into the video you can see a relatively slow light moving from left center to the top left corner. I think it must be a satellite. Then later a line of stationary spots emerges from the lower center extending up and to the right at about a 45 degree angle. They are really in a straight line; because of this, I think they must be internal reflections in the lens. But because they don't move at all, even though the light sources (stars) are moving, I'm puzzled.

NOTE: After looking at this on flickr, I see that the quality is so low that you can't see most of the line of spots.
