- WBPP integration of the 105 subs and 3x30 flats per channel
- ABE for gradient removal of the S,HO masters
- Autohistogram to adjust S,H,O on to same mean and all channels have their histograms centered in the same spot
- ChannelCombination into an RGB Image
So far, so good: great detail, no gradients.
BUT: I either get a massive green or red almost monochromatic image, depending on whether I combine the very much stronger H sub as SHO (green) or HSO (red).
I understand that this is due of the overwhelming intensity of the H channel, so I tried to reduce its intensity with Pixelmath, but that only shifts the bell curve to the left, but does not create a better color mix.
What am I doing wrong or mis-thinking?
Is SHO maybe inapt for the Cocoon nebula (but I had the same problem with Triangulum galaxy)
So how do I get the best result of the SHO data?
Any idea how I must treat the data to get to a decent result?
S,H,O Channels after WBPP integration:

ChannelCombination RGBs with SHO, HSO and a combined version (S, SH, OH)

Neither of these give me chance to to get to a balanced color when I apply curves as they all appera to be fairly monochromatic.
Their histograms of the linear images are all like this:

So I tried to adjust the intensity of the channels, but that only moves the channel histograms sideways, but does not change relative height.
