Dark clouds pass north of Kitt Peak last week in this image. The domes, from front to back, are the Spacewatch 36 inch, Steward Observatory 90 inch Bok telescope, and the Kitt Peak 4-m Mayall telescope. This image was taken with the kit lens on my 20D at 18mm focal length. The exposure was 1/20 seconds at f/5.6, ISO 800.
