Telescope mounted CCDs are usually cooled to -30C with respect to the ambient temperature though, and pointed at very dark sources.

Joe,
This time limit seems strange to me!
Amateur astronomers routinely make 30-minute, 45-minute, and longer exposures with telescope-mounted CCD cameras!

Page 50 of the October issue of Pop Photo has the following statement (in reviewing the Fuji Finepix S3):
"...a black-and-white image is output through the S3 Pro's video connector. (This signal lasts for 30 seconds to prevent CCD damage.)"
Do long exposures damage a CCD? Any of you heard anything about this?
Thanks,
Joe
