An attempt to process material captured in August 2025 in Siril 1.4.1, using new VeraLux scripts (Silentium, Alchemy, HyperMetric Stretch, Star Composer, Vectra). For the stars, the NB_2RGB script was used. In VeraLux Alchemy, the HOO palette was selected.
The NarrowBand to RGB script is used after extracting stars from a narrowband image. It makes the star colors more natural. This is an attempt to avoid additional unfiltered imaging of the object just to add stars from that data.
Class, did the alchemy itself break the channels for you? For some reason, I can't achieve the result I once got with pixel math. I used some clever algorithm, but now I can't replicate it.
Yes, by myself. There are three palettes in the alchemy: HOO, HSO, pseudo-SHO. Plus the ability to tweak the settings. Anyway, I spent the weekend watching Rich from the YouTube channel DeepSpaceAstro and decided to give it a try.

I also use Siril.
What does the NB_2RGB script do?
