PixInsight Scripts
The PixInsight scripts are a theatr.us tool rather than part of PSF Guard, and their guide lives there: Foraxx palette for PixInsight and Photoshop. The palette itself is The Coldest Nights' dynamic narrowband combination.
In short
- In PixInsight, open Resources → Updates → Manage Repositories
and add
https://pixinsight.theatr.us/, including the trailing slash. - Run Check for Updates, accept, and restart PixInsight.
- The scripts appear under Script → theatr.us.
https://pixinsight.psf-guard.com/ still works and
serves the same files. Everything else, from the palette math to every option,
is in the guide on theatr.us.
Why it pairs with PSF Guard
PSF Guard decides which frames to keep and can build the stacked narrowband masters; the Foraxx script is one way to turn those masters into a palette image. Seiza, which powers PSF Guard's stacking, can also render the Foraxx palette directly.
Bring FITS and XISF masters into Photoshop
For a Photoshop finishing workflow, the FITS and XISF plugins open and save those formats directly on Windows and macOS. Choose Float32 or rescaled 16-bit import, then save at the document depth. See Photoshop installation, settings, and file preservation before editing your masters.
