The last image from the Twelve Images of 2008 is from the month of December, and titled through the sky.  Earlier in the month I headed out near the airport and photographed the light trails through the sky.  There was some cloud cover this evening but it wasn’t too thick allowing the stars to appear with longer exposures.  With the sky so clear and airplanes departing it was a matter of determining what the turn of the aircraft would be and quickly composing a scene.  The other element I noticed was the amount of light pollution you would get trying to include the airport in the shot even though we were easily five miles away from the terminal. The below image is a 30 second exposure of an airplane making a left turn after departure.
