Description

This is the same data as in the image processed in the SHO palette:

Here, it is presented in a natural palette. The RGB data that was in the previous image used only for star color provides primary color information, supplemented by the narrowband data with a natural palette and overlaid in Photoshop with Lighten blending mode. Luminance layer was still derived from narrowband data but applied at much lower opacity than in the SHO image.
