Here we have my second attempt at photographing star trails. This was a 16 minute exposure taken at a friend's camp at Sand Bay, roughly 45 km northwest of Sault Ste. Marie, ON.
There are a few 'hazy' patches in this image due to condensation forming on the lens as a result of the cool, humid conditions that night. There were also people hanging out on the dock and swimming during the exposure, and some of that activity is evident in the image.
The original image was quite noisy due to the long exposure, and so I had to perform quite a bit of noise removal on it. Unfortunately, this caused much of the detail of the fainter stars to be lost.
