No Decon, star sharpening, Starnett or any other AI used.
Tried yet another process in Pixinsight.
The Ha and O3 together produced the pink in the core.
Probably over did it a bit but this was an experiment.
Here is the process if you are interested:
1: PixelMath.Isolate the galaxy (Ha, O3) with: iif(inrect(1854,1106,680,1000),$T, 0)
2: Use range selection mask to cover galaxy.
3: Histogram transform to remove background (what's left of it).
4: Repeat step 2 & 3 reducing size of mask.
This reveals the brightest parts of the Ha & O3
5: Combine with PixelMath:
Red channel: $T+Ha*3 Green $T Blue $T+O3*3
Drag triangle onto the LRGB image.
I reckon you did the same thing you did on your previous galaxy shot with the core that Mike pointed out. Other than that the field is essentially perfect. More repros on the horizon.
