This document discusses hacking a Canon camera to take aerial photography from very low orbit satellites using the Canon Hack Development Kit (CHDK) to trigger the shutter button and record time lapse imagery. OpenCV computer vision software is used to stabilize the photos captured. The results from this project and those who helped support it are acknowledged.
