Re: [APML] Foveon Chip

[George Anderson <georgea@cam.org>]

The question are... 
How noisy is the chip with long time exposures? 
Is the chip a CMOS imager or CCD? 
IIRC CMOS doesn't like cooling, or at least it doesn't improve the
noise.

Clear skies and good health
Right now we don't need no stinking cooling devices
