Just my 2c.

Hi Dunk,
A valid point
The 2600 series cameras have virtually zero dark current at -20C
Running at -10C is just taking advantage of the cameras wonderful performance, they’re not cheap cameras
Again I’m pretty sure that it’s the 90% + humidity in Sydney lately that’s causing the coolers suboptimal performance.
Friday we have a 22 deg day with southerly winds and 60 to 70% humidity
I’m confident that the cooler will maintain - 10C with 10 to 15% spare power
Cheers
Martin
