The Big Dipper

We went into one of the rooms of Pueblo Bonito as darkness approached, and set up our cameras on tripods in order to make long exposures of the sky as seen through the open roof. I started making exposures when there was still light in the sky, and continued until the sky was completely black. I was surprised to see that I liked the first exposure when the sky was still blue. By the way, Polaris, the north star, is visible through the window to the left. The big dipper itself is upside down in the center of the picture. Please click on the image to see it larger. It is easier to spot the dipper.
