I followed the instructions and was able to achieve Gain 2 Offset 109 of what I thought was reasonable.
See screenshot...
I noticed I have a few dead pixels? White dots seen when the image is dark.

Get your gain to 0 or 1. The offset will determine the position of your histogram in respect to the left side. Varies on cameras and sky conditions. I use 60 to 70, that gives me a sky background of 900-1000ADU typically. You want that margin on the left, no more no less. 1000ADU is comfortable to play with. No clipping.
