KPNO 4-m Mayall Telescope
Guess where I am tonight - Ok, the photo gives it away. I am at the Kitt Peak 4 meter Mayall telescope learning how to use the Mosaic camera for a Target of Opportunity observing program this spring involving WISE spacecraft discoveries. This image was taken in twilight as the telescope was being prepared for the night. Unfortunately, the humidity has closed us down for the time being, but it's fun to type this from the control room next to the telescope. This image was taken with my 10mm fisheye lens with an exposure of 1/10 seconds at f/2.8, ISO 400.
