Star Trails

First attempt at shooting star trails. Used the zoom lens and shot a 567 second exposure at 18mm and f/22. Since I'm in the city, I was expecting a lot of light pollution.



The resulting image was very dark so I had to use Picasa to change lighting/contrast to see anything. I made sure I was pointing north and you can kind of see Polaris as a single dot (no trail) between the power lines. There's also a few noisy pixels and a lot of shadows, which means I need to clean the lens.

I read online that a lot of the star trail photos, especially ones with really long trails, are composite images. Since my camera takes almost the same amount of time as the exposure time to process each image, not sure how I can shoot multiple shots without long gaps between each shot. Probably a camera body with a faster image processor.
