I prepared Canon 350D with remote controller some days ago. The tripod is from my small astro-telescope.
The email from HQemail@example.com said this:
Time: Fri May 23 4:15 AM, Visible: 4 min, Max Height: 66 degrees, Appears: W, Disappears: NE
My location was the road between Bratislava and Kittsee. There I aimed the camera somewhere to the sky. With 18 mm lens (Canon EF-S 18-55mm, f/3.5-5.6) I was not afraid that I miss the flyby of the station. I took some testing shots just to be sure. The sky was quite bright around 4 am therefore I set ISO to 100. The lens focusing was set to manual mode.
I couldn't see the station exactly at 4:15 most probably because of the morning haze. Suddenly it appeared and with full of joy and excitement I pressed the shutter with remote controller. I assume the exposition was around 1.5 min.
After processing in iPhoto and GIMP here is the final image (my first photo of the ISS!):
