Star Trails - 4th Nov 2013

This image was originally intended to be a timelapse video of around 500 frames.  However my lens got covered in dew after around 75 shots, so I scrapped that idea (along with 425 shots :( ) and stacked them into a star trail picture instead!

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.
