LOL, yes I guess I am the one spoilt. I don't like it when I can't get -35C in the 16803 and have to settle for -30C! The Microline does -40 most times and -35 almost all the time. It is the zone for CCDs. Beyond -40 there is probably hardly any noticeable gain but -30 to -40 is pretty clean.
Still I am sure your QSI is still very clean compared to older CCD cameras around.
