Im a bit confused. At less that 0 c, I got hard frost on the finger and dew on the sensor, yet you dont have dew at -11c, how do you avoid that?.

When you always keep an filter on the camera, the air in front of the sensor is very moisture free.
As soon as i take the filter of, moisture can get to the cmos.
This has been a problem with every camera, as long as the air in front of the cmos or ccd is dry, it will not dew up the ccd or cmos.
At the moment i am imaging and it is on -14.6C.
Will post a raw pic without processing i about an hour or so.
The pic is just about without any noise
