Here is some fun for you.
Going through some old storage boxes I found a CD with some star trail images which I had taken over sixteen years ago with my Canon F1 film camera. The lens used was a Canon 28mm prime lens. Exposures were about one hour for each image.
I have uploaded them to my flicker account

Ah, the fun we have when we find old data lurking about.
Cheers,
