In this Hubble Palette version (SHO) the H-Alpha is mapped to green channel, SII is mapped to red channel and OIII is mapped to the blue channel. The raw data was preprocessed using Pixinsight, the stars were removed using a tool called Starxterminator and the stars were later replaced during Post Processing in Photoshop CC with the more naturally colored stars from the RGB data.
Captured bin 2x2 over 4 nights in October 2022 for a total acquisition time of 13.73 hours.
