Space Station sunset

It was sunset time aboard the International Space Station during this photo taken on Tuesday night (June 10) from Kitt Peak. The ISS (with shuttle still docked) was moving from the upper right to the lower left as the sun set below the horizon for them. The bright local moonlit sky provides an interesting contrast. Notice how the trail of the ISS goes from white to a redish brown before disappearing completely. This image was taken at 24mm focal length with an exposure of 30 seconds at f/2.2, ISO 400. BTW, if you look at the full resolution image, you'll see a fuzzy blob almost directly below the ISS trail - that is the huge globular cluster "Omega Centauri" and the ISS is trailing through the northern part of the well known southern constellation Centaurus.
