As it was a fine clear evening I decided to have a go at taking a star trail picture tonight. After some trial exposures I settled on 800 ISO with 30 secs @ f4 which gave a good result for a single image. I then set the camera to continuous and recorded 99 images over an hour. These were stacked together using Star Trails software. As I live in a town I set the white balance to the lowest colour temperature possible to remove the orange glow from the street lights. I was quite pleased with the result for a first attempt.
