Hi all,

I just wrote on my blog a post about CHDK
I used it during the last meteor shower to try and catch them, and also made animations of moving stars.
Here are the animations

Hope enjoy it
Guy

If by ampglow you mean the light at the top edge of the frame. Then I have a bad feeling its the chip warming up from long exposure times and the intensity of them. Also there might have been light pollution

Yes, but the ampglow should only happen with really long exposures, like 2+ minutes or more, so that's why I asked what exposure you used.

I'd guess you had dark frame subtraction off.

The link in the first posting is broken. It should be http://guysoft.wordpress.com/about/videos-of-sky/
