I checked the statistics in Fits Liberator . The standard deviation I think shows the level of thermal noise in the dark frames and at 35 degrees it is 16, at 23 degrees it is 9 and at 14 degrees it is 5.9. The peak is 200, 185, 37 respectively , all humped on the left at 14 degrees. Seems a big improvement.
I have seen projects with large crystal desiccant used in filling the unused ST4 port. I wonder how different it is when using the camera cooled at this level than using it outdoors at 5 degrees which is probably what the minimum outer casing is.
Like a nice cold beer. Perhaps it will work bolted to the base of my sealed DSLR if I keep it in the fridge in a bag with some desiccant first.
