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

Camera
     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.
