Siril script for Seestar CFA extraction and stacking

Hello everyone,

for what it is worth, I would like to share a small Siril script project for Seestar FITS images:

It lets the user select which CFA-derived channels to extract from Seestar FITS data — L, R, G, and B — and then provides stacking workflows for the selected channels. A particular focus is photometry-oriented handling of FITS header values such as exposure time, observation time, combined exposure, and the number of stacked frames.

The motivation is that in many general-purpose workflows these header values are not always preserved or documented in a way that is ideal for later photometric use.

This is not a full photometry tool yet. However, an extension towards a complete photometry workflow is already in development.

I would be grateful for tests, feedback, bug reports, or suggestions, especially from users working with variable-star photometry and Seestar FITS data.

Best regards,
Thomas

Hi Thomas,
I’ll try it.

Best regards
