Desperately suffering cloud fever here...
I had some clear skies to the east this evening, so thought I'd try some star trails. 125 x 30s exposures, 5 darks, Olympus E-510, 200ASA, Zuiko digital 8mm fisheye @ f/5.6. Stacked in Startrails.de and post processing in PS. Cloud affected towards the end...
