Of halos and telescopes
Cirrus is keeping me from observing, but not from getting pretty pictures of the sky and telescopes on Kitt Peak. The Moon is producing a nice halo (unless you're trying to observe faint asteroids and comets in which case it is a bad halo). At lower right is the Spacewatch 36 inch telescope dome. This image was taken with my 10mm fisheye with an exposure of 30 seconds at f/2.8, ISO 400.
