I am publishing this image in coordination with a recent narrowband result. 
I think this image, though just an LRGB and much less color differentiation by comparison, highlights the detail in the center of the nebula (the large telescope helps!).
This was the state of the art processing for me at this time in the Fall of 2014. This is before BXT and even before PixInsight for me (I would first dive in the following year). 
I think it still holds up- and might be useful as a reference here on Astrobin.
