432 images with a shutter time of 32 seconds and an interval of 34 seconds were made by a Canon A610 + CHDK. Then I processed the images in three different ways using Python scripts and the PIL module. First you can see the original images with a time stamp. In the next sequence, all images are stacked on top of each other, resulting star trails. And finally, the trails fade out by reducing the brigthness of previous images.
