I will dig up some darks and post them.
That is a cracker of an image by the way  !

Here you go:
I didn't have any 300 second darks at the same ISO - but this is a useful comparison anyway.
1st image: 300 seconds, 400iso, 38 degrees
2nd image: 300 seconds, 800iso, 26 degrees
these are 300x300 pixel crops from the upper left of frame
