One last image from Cornwall. The cottages we were renting were just a 100 metres or so from the beach and maybe 1km from Sennen itself. With no other town in sight, the beach was free of light pollution, making it a perfect location to try a star trail image.
The beach was a little short on foreground interest, but we managed to find a few low lying rocks. We then sighted up on the north star to get a full circle. The final image is a composite of 67 separate 30-second exposures at f3.5 and ISO800, all blended using the software available here. For the last 10 seconds of the last shot I painted the rocks with a hand held LED torch.
For a first attempt at this technique I am pleased with the final result. In the high resolution original it is possible to make out the different colours of different stars. I am really looking forward to my next chance to try this again, hopefully in a location with a stronger foreground.
