4-m Mayall Telescope

The 4-m Mayall Telescope on Kitt Peak is prepared for a night of observing asteroids. This image was taken with my 10mm fisheye lens as we set up for the start of the night.  The exposure was 8 seconds at f/2.8, ISO 400.

Space Station, clouds and domes

The International Space Station appears over Kitt Peak on November 3.  The ISS was traveling upward and passed into the Earths shadow, fading out at the end of this exposure.  Also in the frame is the Spacewatch 36 inch telescope at center and the Bok 90 inch and Kitt Peak 4-meter telescopes to its right.  The Moon provides lighting for the domes, the landscape and the clouds, making the scene appear almost like daylight.  This image was taken with my Canon 20D with a 10mm fisheye at f/2.8, ISO 400, 60 second exposure.
