The following picture of star trails was taken by Chris Newsome on the 25th September 2005. He used a Canon 300D
camera with a 55mm lens at f/5, 100ASA, and a 40 minute exposure. The camera was pointed at Polaris (the bright star in the lower part the
picture). Dark frame subtraction was made in K3CCDTools and the final image processed in Photoshop v7. |
