Notes
re processing: The Pure RGB from PixInsight (Photometric Colour
Calibrated) was split into R, G and B in Photoshop. The H-Alpha was
blended into the R and B channels at 80% and 15% respectively using
Lighten blend mode. Then the RGB was recombined. Subsequent to that,
the H-Alpha was added as a Luminance layer to bolster the overall
image. This was blended at 20% to avoid a major colour shift. A
subsequent curves layer was used to boost contrast. Below is the
12 hour H-Alpha channel alone for comparison:
