Star Trails - 4th Nov 2013
It is a stack of 75 frames, each of which is a 15sec exposure at ISO 800 on my Canon EOS 550D. Long exposure noise reduction was switched on, in the camera settings, to get rid of the dead pixels and also provide a delay between shots. Stacked and tweaked in Photoshop CS5.
The Andromeda galaxy is actually visible as a smudged trail in the top center of the image.
