As the morning twilight grows in strength, telescopes on the north end of Kitt Peak prepare to shut down. In this image, the Spacewatch 36 inch telescope left of center is visible with the Steward Observatory 90 inch Bok telescope and KPNO 4-m Mayall Telescope near center. Just right of the 4-m is the glint of an Earth orbiting satellite. The Big Dipper is near the top of the frame. This image was taken with my 10mm fisheye lens with an exposure of 59 seconds at f/2.8, ISO 400.
