Fog on Kitt Peak
Not too much observing tonight on Kitt Peak, and here is the reason: fog and high humidity. Here, the Spacewatch 36 inch dome pokes out of the fog rolling over the mountain top. The 1.8-m dome is also visible to the left. This image was taken with my 10mm fisheye lens with an exposure of 30 seconds at f/5.6, ISO 400, and cropped a bit.
