After admiring Dean Ketelsen's amazing Kitt Peak sunset images, last month I had an idea for a spectacular image of the Moon setting behind the 4 meter Mayall telescope on Kitt Peak. I predicted the where, and when this would happen and subsequently made this image. The image is real - the only photoshop used was to composite the individual 7 frames of the scene taken at 1.5 minute intervals. Unfortunately clouds obscured the moon just prior to the actual silhouette.
The images were obtained with a Canon 5D mark II camera attached to a 400mm lens and 2X teleconverter for an effective focal length of 800mm.
