Great shot! How did you achieve a Hubble-like palette using only Ha and OIII (judging by the technical details)? What blending formula did you use? Or did you simply forget to mention sulfur in the details?

Thank you! This is the Foraxx palette. Yes, I use only 2 narrowband filters and combine them using a script by Paul Hancock (PaulymanAstro). You can read about how this script works here: https://remoteastrophotography.com/2023/01/foraxx-palette-script-dynamic-narrowband-combinations. I've also tried it with three filters—I didn't find much difference. If you add SII, the yellow color shifts closer to orange. In my opinion, using just 2 filters actually produces a more interesting result.
