This is the second night that I just pointed the camera up and let 'er rip..
I'm using a Canon Powershot A560 that's using CHDK to take 65 second exposures and do the timelapse. This version is using the raw exposure (also thanks to CHDK).
My processing sequence went something like: raw .CRW -> dcraw -> png -> virtualDub
I used a few filters in virtualDub to adjust the levels and the overall color.
You can see some sort of pink ccd noise in the upper left corner... I need to take some dark frames.
Exposure info: 65 seconds, ISO 1600
I left a 20 second delay between shots to let the ccd cool down.
