Watching The Skies

The post sunset glow behind one of the radio telescopes that forms part of the Mullard Radio Astronomy Observatory.  It's a shot that I have been been meaning to try for a while.  The original intention was to have a go at some start trail shots as well.  I waited for an hour in the cold after this picture, but it still was really dark enough.  I could decide if it was the very last glow of the sun or light pollution from Cambridge.  I will have to try again at a later hour.
