I get the same thing, only I have a lot more hot pixels, to the point where I'm almost ready to ask Theo if it's normal to have so many. I made a bad pixel map in Neb2 last night that seems pretty good, I'll attach it.
As I want to make some reliable Darks and Flats now, I also did the Test as described in
http://www.cool.id.au/astronomy/Neb_tut/ by Benko and Felix, which I think is also here on IIS if you do a search. My results were good apart from the unexplained drop in mean from ~64000 to 32742 at saturation (Gain 10). Any comments on this are welcome.
Anyway, my final settings appear to be G9, Offset 115, and they seemed to work OK last night, although still lots of hot pixels in my normal 5 minute exposures.
I was hoping to do a new set of bias, darks then flats at this setting this afternoon, but it's 42C in the obs and the poor old QHY9 will only hit -14C at the moment.
Hope this may assist the OP.
