A very unusual palette! But that doesn't make the image any less interesting—quite the opposite.

Experimenting with the Foraxx palette. There's a script for Pixinsight by Pauliman Astro. It requires either a full set of Ha, OIII, and SII, or just Ha and OIII. I don't have an SII filter, so I'm using the second option. The brightness of pixels in the final image is calculated dynamically by the script. Where there's more hydrogen, it results in a red color; where there's more oxygen, it's blue. Where they're more or less equal, you get shades of yellow and orange. But since the script only works with non-linear images, the result depends on how you stretch them. OIII is usually significantly fainter, so I have to stretch it very aggressively. But the results are usually interesting.
