Space Station over Kitt Peak
The International Space Station (ISS) made a nice pass over Kitt Peak for the 2nd night in a row. Here it is seen trailing through the constellation Cassiopeia and over the 36 inch Spacewatch Telescope dome (with the 90 inch Bok telescope and 4-meter Mayall Telescope domes at right). The orange glow is not twilight - that is the glow of city lights from Phoenix and Casa Grande. This image was taken with my 24mm lens with an exposure of 30 seconds at f/1.8, ISO 200.
