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 approx. 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.

I had no watch or stopwatch handy, so I had to count the 40 seconds in my mind: One, two,... Therefore all times are estimated times only.

This technique shows the constellation as well as the star colors.
