The camera was running at -35c and 68% power. But at any temperature the 16803 sensor seems to have less "salt and pepper" than the 11002 series...plus the QE boost toward the red makes 1:1:1 ratio RGB colour exposures very comfortable.

Being able to set the pick-off CCD's focal plane also makes guiding a bit tighter due less bloat in the guide stars. Suffice to say the AO-X is on order..but I suspect still some months off...
