Taken with an umodified Nikon D300 and 35/2.8 PC Nikkor.
24 x 6 second images at f5.6, ISO 1600, normal photo tripod, stacked in DSS and processed in photoshop to remove light pollution. (auto levels (get it visible) despeckle, remove dust and scratches, (which gets rid of the stars) small gaussian blur, then combine with the original using difference mode (which removes the orange light pollution gradient).
