ISS & the Shuttle

We were presented with a decent pass of the International Space Station and the Space Shuttle Atlantis. They undocked yesterday and Atlantis is scheduled to land tomorrow. The ISS leads the shuttle in this view and produced a brighter trail than the shuttle. The spacecraft are moving left to right and Polaris, the "North Star" is visible just above center above the trails. The right end of the leading ISS trail is just beginning to fade as the ISS passes into the Earth's shadow and disappeared a few moments later. This image was taken with the kit lens at 18mm focal length with an exposure of 30 seconds at f/3.5, ISO 400. The bright glow of the city lights of Tucson provides the dome of light extending up into the sky.
