Just curious as I gave a talk to the ASV guys on this topic last week.

Andy,

Neither technique was used.
The objective was to avoid any blending of the Ha and R data to form a new luminance as some contrast is lost when compared to a straight Ha luminance.

The procedure is to process a HaRGB image in PixInsight. This does a good job in maintaining star colours without any HaR blending.
The resultant image however has the typical salmon pinkish colour of using a straight Ha luminance.
The pinkish colour is removed by using the shadow highlights command in Photoshop in reverse as is the usual processing procedure.
Here the shadows correction is set to 0%, while the highlights tab is shifted to the right until the pink is removed.
Further tweaking of the colour balance is done against a straight RGB reference.

I have used this procedure on this NGC3247 as well.

The silver stars with rings could be worked on, maybe cut and paste the RGB stars back in?.. aaaand the decon is a tad obvious in the bright areas, other than that great stuff

Mike

MIke,

Strange the decon is a bit obvious as no deconvolution was used. Only a touch of a wavelet filter was used.
