I build cameras with Raspberry Pi computers to watch the sky so I don't have to. It's mainly about meteors, but also whatever else happens to pop up.

Last Night's Images

Keograms show sky conditions minute by minute through the night.

Startrails reassure you that the earth is still spinning.

Animated startrails tell you which way it's spinning.

Timelapses stitch together all the night's images into a short video.
