660RE: [ccd-newastro] Re: Ice Crystals
- Nov 1, 2000I had a case where the o-ring that seals the chip chamber was kinked at the
time the chamber was closed, and this allowed moisture to get in big time.
The camera had to go back to SBIG for examination, and they figured out what
had happened right away and fixed it quickly and easily.

Man, this is Murphy's law to the Max, I am looking at a sky full of
Milky way and my camera is frosting and forming crystals.
I have been keeping my camera attached to my scope inside the
HOMEDOME without putting it back in the case for the last three days,
the ambient humidity has been only about 20% the last few days.
Could this cause my camera's decicant (SP) to prematurely fail????
