That looks very nice and I think you have caught some of the IFN in the first image too.

I was hoping that was what it was, I am still working on bringing it out, so there could be an amendment to follow.

Yes indeed there's IFN.
But I see something strange with colours - like they are nor aligned or something.
Looking at brighter stars there's blue/purple at left and yellow at right.

Had a bit of a mare with that Einari, its aligned as far as I can see, but still getting colours in the halos.

There's a lot to be said for dark sky camping sites.  Unfortunately, it's the "camping"  bit that puts me off... 

I'm amazed at the great results you get with relatively few subs.  Do you beat noise down with processing or are the subs clean anyway?  Mind you, my old SXV-H9 lacks set-point cooling.  Maybe time to get an ATIK 460 like yours..

Noise varies with the target I am trying to get and what I am trying to pull out of it.

This one in particular because I was trying to get the IFN I was having lots of problems with revealing noise.  Narrowband seems to suffer less.

I do think I need to take some better colour subs for this target though as I really skimped on it because it had worked on previous images.
