I admit I tried this late last night (probably too late), and I'm not sure I'd call it enjoyment. lol.gif

 

Is this just a stack of lights?  Boy I had all sorts of crazy things on the screen and couldn't figure out what to do with it.  Noise?  Gradients?  Light leaks?  Thermal pattern?  Maybe nebulosity, maybe IFN dust, maybe...who knows lol!

 

Your image looks good.  Maybe that's what it takes here, just squash it all down with a limited stretch except the blue center?  15+ hours though it'd be great to reveal even more around it.  Might try again later...

Nice image! 15 hours!
I also shot this the other night. I’ve stacked it but that’s all. I’m not sure I got any nebulosity to work with. I think I’m too impatient to gather enough time. I’m like a kid in a candy store, I want to taste each one but I don’t take the time to savor any! Haha

Honestly, I'm extremely dissatisfied with the stack, that stack has no DFB because when I tried the DFB it looked worse. 
I'm sure my exposure is FAR to left on the histogram, and eve so, was blowing out the core double star.  I think this would benefit, from another round of center historgram to bring out more of the dark nebula. 

I'm not sure what is going on with the data, but since I have been shooting an hour here and an hour there, in bortle 6 or 7 skies, over the course of time there has to be differences enivormentally, etc.

As said above I think this target would benefit from some center histogram, and then some left histogram, and merge the two stacks in post.
Give it a go, or post your stack, I'll play ! 

Thank you !!!

Clear Skies !!
