I'm up to 5 hours on M81, and wanted to share where I am so far for feedback and encouragement.

Flats are driving me nuts! ....so, none
Stacked in DSS, processed in PI
I am liking where this is headed. I think that perhaps another night or two will be as far as I want to go with the LP in my backyard. Thanks for taking a look, any C/C is welcome.
Oh, and in case anyone wonders why the crop is a bit tight, I had some pretty crazy stacking artifacts at the edges when I put together the two nights (didn't match the framing as well as I should have), so had to crop it pretty hard.
