Just a quick update regarding sensor cooling.

Testing has been done indoors with ambient temperature of 23.2 C and cooling set at 100%.

After 1 minute CCD temperature dropped to -4 C
After 2 minutes CCD temperature dropped to -17 C
After 3 minutes CCD temperature dropped to -22 C
After 4 minutes CCD temperature dropped to -23 C
After 5 minutes CCD temperature dropped to -23.3 C and stayed there.

That gives 23.2 +23.3 = 46.5 C below ambient at 100% cooling (indoors)
With CCD temperature set to -20 C (43.2 C below ambient) it required exactly 80% of power to maintain that temperature.
With CCD temperature set to -15 C (38.2 C below ambient) it required 69% of power to maintain that temperature.
With CCD temperature set to -10 C (33.2 C below ambient) it required 58% of power to maintain that temperature.
