I collected more data on the Rosette Nebula, and gave it a reprocess. This time I tried out the new Veralux narrowband processing scripts in Siril to produce this pseudo-SHO image.

I based my workflow on Rich's Deep Space Astro tutorial, with a few changes. The tutorial is here: https://youtu.be/8UEDg_vCPWc.

The first situation I ran into was that some of the surrounding O3 looked splotchy after I upped the O3 gain in Veralux Alchemy to bring out the core. I opted to forgo the O3 gain in Alchemy and instead wait until I was finished in Siril. Then I bumped up the cool temperature in the core in Topaz, where I had masking tools.

The other thing I did differently was to skip the narrowband to RGB script for the starmask, and instead run it through the Veralux HyperMetric stretch, and then recompose the starless and starmask versions in Starnet++. I mean, it's already a false color palette, so it's pointless to worry about the star color police, right?
