Thanks all
Yes there was a fair amount of hot pixels, but Iris does a great job of removing them, even if the darks were not taken at same temperature, one draws a small box on a dark area of sky with no stars in the box, just hot pixels, Iris then adjusts things to see that the proper amount of subtraction is done, without either leaving too much noise, or dark spots caused by too much subtraction. Was nice and warm siting there guiding lol.
seeing wasnt the best though, in the warm air, somewhat unstable.
