Stacked R, G, B, and CFA data. Split CFA data into R, G, and B channels, then extracted stars and ran PixelMath of max($T,CFA[channel]) on each monochrome file. Discarded CFA and cloned R, G, B. Stretched and extracted stars. On the non-clones, exterminated stars and ran unsharpmask iteratively followed by a Masked Stretch set to .2 background. The normalized background was combined using LRGB and denoised. Use a combination of ExponentialTransformation and slight curves adjustments to bring out details in the dust.

Can't get enough of these winter sapphires. It all started with the thought, "What would it look like if I combined my monochrome camera data with the one-shot color data that I captured with HyperStar?" The answer...
