Used CHDK to take these images of the International Space Station on 9-22-08:

Canon PowerShot SD750
ISO 400, +2EV
1/1000 sec. exposure
Used CHDK to
override exposure to 1/1000 sec.
continuous shooting script
turn noise reduction off for faster shooting
Camera was attached to the eyepiece of an Orion XT8 8" reflecting telescope and hand-tracked to keep the space station in the field of view. Distance to the space station: approx. 230 miles.
I used +2EV instead of increasing the ISO due to less noise at ISO 400. With CHDK, this camera can take more shots per minute (approx. 100) at ISO 400 than it can at ISO 800 and up.
