Hi Jeff and Stephen;

Very cool. Thanks for sharing.

When the Leonide peaked in the early 2000's, I recorded several hours of it using a DV Camcorder when I was in Ottawa Ontario Canada. I'd written a Quicktime app back then that analyzed the hours of video footage, could detect the abrupt change in brightness from the meteors and would then generate a short reference movie about 1 second before and one second after it occurred. Took maybe 5 minutes under OS 9 on G3 laptop to scan through say 4 hour of DV Footage and generate the ref movies of it. I also used it for detecting lightning strikes too, which I used to enjoy recording with the dV Camcorder.

Now a days,I could probably do that in real time - revolving files recorded to disk and then over written if nothing happens. Unless the clouds were really low  and moving fast (or lit up by a moving light source), they likely would not trigger a capture event either.

My code did catch a lot of plane traffic too.

TTYL..

I always enjoy grabbing pictures of meteors. AstroIIDC was used to control a firewire camera with a cheap lens to grab the images. 

Great software for video astronomy. 

I caught 17 over the night of Aug 11-12. Had some clouds at the start but it cleared shortly after midnight. In fact, I really like the first picture with the clouds.
