@Raúl Hussein I'm sure you're aware of this, but in my experience a linear fit (called linear match on Siril) makes the blue colours come out more easily and still be natural. Right after RGB extraction, adding this to the Siril script gets the job done: # Linear match with respect to the R component load G linear_match R 0.0 0.92 save G load B linear_match R 0.0 0.92 save B

Paul Lloyd:
Raul,
This looks to be a very welcome addition to PI's arsenal, and I join with others and thank you for making this tool available.
I don't know whether it's already been raised, but there are dual band filters like Antlia's H-I+O-III and S-II+H-II now available for OSC cameras. Would your script be able to process these so that all 4 emissions can be isolated, then combined as desired? I'm particularly interested, here, in making the H-II speak for itself, so a final RGB combination that shows the H-II with its own colour (magenta?, gold?, ??) would be helpful. As I understand it, H-II regions show the existence of very hot, young stars and, therefore, indicate regions of active starburst. From an imager's perspective, H-II regions would overlay H-I regions, but are likely to differ somewhat in their structures.
Paul. Hi Paul, excellent idea. I’m back to working on the development of a new version. I believe what you propose is feasible, and I’m adding it to the TODO list. I hope you’ll be able to see it shortly. Thank you for the suggestion, and sorry for the delay!

save B Hi "madrileño" hehehe The function of the script is not to create the palette, but simply to display it as an example. Based on the channels, proceed with them as you see fit. Are you familiar with Autopalette? It will be integrated into future versions. I’ll forward the query to Edu to see if the script can be improved. https://autopalette.astrocitas.com/ |

Pedestal normalization: the background (pedestal) value was subtracted to isolate the signals before applying the formulas for each sensor. Finally, the pedestal was added back to avoid clipping. This is based on robyx's comments in the following post.  Blue channel vs OIII extracted  |

Thank you, Raúl! Great to see this tool is still in active development.
Any chance the Siril scripts will also be updated to keep them aligned?
Saludos desde Madrid!

Saludos desde Madrid! Thanks. Currently, they have the same capabilities except for being able to define custom QE.
