	Optics: Hasselblad/Carl Zeiss 4/120mm Detector: Kodak Ektachrome E200 Prof. 6x6 cm Exposure Time(s): 30 minutes Moun: Fixed mounted on a photo tripod Processing Info: PhotoShop Notes: I focussed this image progressive. I started with a totally defocussed setting. During the exposure, I changed the focus every 40 seconds in 'infinity' -direction. Before the end of this sequence I covered the lens for two minutes before I let the light pass again for about 10 seconds. This last exposure time made the sharp star at the end of each trail. This technique shows the constellation as well as the star colors.
