This is to go with the M-82 pix, 65x360sec stack. Shot on AT10RC with QHY12 OSC.

Your RC sure pulls in the detail!
As for the last one, we can't beat the atmospheric fluctuations that mess with our attempts.
I'm hoping to get out tonight before the Moon comes up.

Thanks Sonny, 1 more try. Heading to the desert next weekend, it'll be nice to get rid of my red blotchy background, or at least I hope.

What are you using to do the initial alignment and stacking? Deep Sky Stacker? If DSS, I can see why you're having problems dragging the galaxy out of the background murk. You should have more than enough photons in 65x360sec with a QHY12 OSC to really showcase this galaxy! M81 is a fairly faint galaxy and needs a narrow differential stretch to pop it out of the background, i.e.: very little difference between the outlying arms and the background.
Would you be interested in having me take a shot at processing your subs? If so, send me a few subs via private message or DropBox (at bwallan@abkaent.com) and I'll gladly take a shot at it. No promises but I need something to tackle at the moment...

Good luck and have fun in the desert clear skies.

I would love someone to take a crack at it. I use nebulously for stacking and preprocessing. My individual images are about 27meg. Stacked is around 70...I’ll see if I can get the stack on Dropbox.

Sent to Dropbox. Wasn’t really sure what I was doing, but your should have gotten 2, hopefully in one of those.

Thanks. I played with the 1 Master Stack.tif file in PixInsight, (mainly) Photoshop and Lightroom. A couple of renditions below.
Remember, I like color...

How do you get the nice smooth and “black” sky? Mine is always red and when I stretch it is red and black blotches. I spend so much time because of that.

I didn't have any problem with the background. It was almost perfectly flat and really nice to work with.
I simply loaded your image into Lightroom, hit Auto and Cropped it the way I wanted it. I saved it as a TIF file and did a Masked Stretch in PixInsight. I got the attached result.
From here I loaded it into Photoshop for a white balance and an attempt to pull more of the galaxy's arms out of the background.
