Mike. Not sure how I am categorised an expert. All of the material in my publication is available to anyone with an inquisitive nature. It just so happens I decided to put it in one place.
It makes sense that consistent temperature across a data set is beneficial. CCDs demonstrate that clearly. My point is, that very low temperatures, while reducing dark current significantly, can be problematic technically, in DIY systems. Go for consistency and take darks. Temperature regulation makes it easier to compile libraries for long term use.
The biggest issue is the camera getting wet. Sort out the protection requirements and then work out the cooling system details. As yet no one has come up with a really efficient cooler box. But Glen's argon bag is a clue.
