Long exposure infrared (760nm).
Nigg bay, Girdleness, Aberdeen.
This may be a good place for star trails, come winter. I think I'll have to wait until winter as it'll need a very cold night to get the haze out of the air - there'd probably be too much reflection of light pollution from Aberdeen on anything but the clearest of nights. Besides, the sun sets too late at the moment!
