Description

Another in the Sh2 series.

Revision based on systematic study of the AIP HA settings:

Lightness set to 100% to bring out the detail in the HA, but this will produce salmon red color.

Thus set saturation to 30%.

Then increased HA in Red channel from 33% to 66%.

Believe it or not went through star-reduction.

I did do selective saturation increase on the Red to counter-act the high lightness from the 100% HA.
