Here are a couple I did a few months ago:

This is a series of 9 8-second exposures of the International Space Station passing through the constellation Orion, 10-24-08.
Used Startrails (http://www.startrails.de/html/software.html) plus Photoshop to adjust levels.

This is the full series of 31 8-second exposures. Used DeepSkyStacker (http://deepskystacker.free.fr/english/index.html) to keep the stars aligned.

Camera: Canon PowerShot A560, 8 sec. exposures at ISO 400
Used CHDK for continuous shooting and turning noise reduction off for shorter delay between shots.

camera: canon a550, ISO 50 (?), IS, review, LCD, NR off, about 130-140 64 sec. exposures, stacked with startrails, no darkframe subtraction.
the images were heavily light contaminated, so i had to decrease gamma greatly, and enhance contrast.

anyway, that ISS shot - GREAT!!! nice job!!!

<edit> funny, picasa can't display photos correctly, moved to flicker </edit>

And these two photos clearly show the different results that you get using Stairtrails vs. DeepSkyStacker. Fixed stars with rotated landscape or vice versa. Excellent shots, looking forward to have some nice weather1

Clear skies, jrlasers and dom-a!  :)
