I realised after my post that I should have clarified that I am primarily interested in and talking about short exposure night sky scene images.. ie. images up to about 30 seconds long, both as stand alone images and for timelapse sequences. I think shot noise then dominates in single short exposures right?

Once you start talking long, multiple exposures then for sure everything else becomes far more significant and cooling the DSLR becomes hugely important.
