Sunrise approaches

This view of the north end of Kitt Peak was taken well before sunrise and handheld with my 24mm lens. The telescopes visible here (or at least their domes) are, from left to right, the Spacewatch 0.9-m telescope, the Stewrd Observatory 90 inch Bok Telescope and the Kitt Peak 4-m Mayall Telescope. This image was taken with an exposure of 1/50 seconds at f/1.8, ISO 1600.
