This was made with a 50mm lens and a technique I created in July of 1982. First, the rock wall was focused on and the lens set @ f/16. The shutter was opened and the wall rendered with an electronic flash. Then, with the shutter still open, the focus was shifted to infinity, and the lens opened up to f/2.8 for the remainder of the 15 minute exposure.
Here you see star trails wheeling above one of the chalk pyramids at Monument Rocks National Natural Landmark. In the small window is Polaris and several fainter attendant stars.
