I posted this shot also on another forum, but here I want to emphasize that thanks to the smart brain using the recommended settings, I got my best shot of this faint target to date. Also, I now take darks right after an imaging session and apply a offset of 40, even though it should not make a difference when I take darks with a cooled camera. I only shot 80 2-minute exposures and shot 40 darks with my Maksutov-Newtonian MN190 from Skywatcher. I stacked in ImagesPlus 6.5 and used AstroFlat Pro to flatten the background.

I forgot to mention, I also used a Bahtinov mask, and the focus aid in Sharpcap to get optimal focus.

That's a lovely image from what many people would think was a sensor best suited for planetary work - well done!
