I am sure I could get the background better with the full size tiff.

Thanks for that. Its certainly an improvement.
What do you mean by a false luminence layer - is that a mask? I suspect its similar to the technique I've been using in PI
I've been using Channel extraction to create a new luminence layer, clipping the black with Histogram Transform, applying it as a mask, inverting it and then playing with the Histogram Transform tool to bring down the black. I hadn't thought of using Curves instead to beat down the noise in the background.
I'll have another play tonight. I collected another hour of L last night so I can add that too.
