Lots more hiding in that data as you can see!

I ran:
SCNR to remove the green, followed by BackgroundNeutralization to remove residual blue (though the stars remain a touch cyan), then a ScreenStretch loaded into HistogramTransformation to stretch it while maintaining the structure fairly well. Blew out the core a little, but you need to tweak the main files NOT to (a single JPEG is NOT the place to maintain structure well )

You CAN do the same in PS, but never really looks as good because of how PS handles the dynamic range IMHO.
Thanks Lewis,

I figured there is more than what I could see... I'm just not that good at dragging it out yet.. plus, I'm a cheap old fart and have enough trouble working PS, let alone trying to learn a different app for Astro than what I use for my regular photos.

Happy to link up the original TIFF for anyone who wants a go at it.
