Description

Color obtained with Rob's formulae and procedures:

Add in O-III to Green and Blue:

"In the RGB color model #00b8e0 is comprised of 0% red, 72.16% green and 87.84% blue."

Have blended in my OIII data to my green channel data at 72% strength and at 88% strength into blue.

You can do this by:

1. using (DNA)linear fit to normalize the signal strength of your OIII to the green channel,
2. then use pixelmath to scale the OIII to 72%,
3. then average the green and scaled OIII.

repeat for blue channel on a fresh copy of the OIII.

After this I added in the O-III also as a false L to provide the detail inside the sphere.
