4-Meter telescope in moonlight

The 4-meter Mayall Telescope atop Kitt Peak is bathed in moonlight as we use it to observe Near-Earth Asteroids observed with the WISE spacecraft.  This shot is taken with a 10mm fisheye lens with an exposure of 120 seconds at f/2.8, ISO 400.

Nicely done James! Next time you are up at the 4m - let me know - you can give me the insider tour! :-)
