About this image

Barnard 343 is a dark nebula formed of dense clouds of cold gas and dust but being a widefield image, the adjacent area also incorporates a vast, complex HII region. It’s an interesting subject but unfortunately very difficult to process, due to its notorious so-called “brown soup problem”. The issue is not signal strength but colour separation and contrast, which if not controlled turns everything brown and muddy! Sure enough this was the initial outcome using a conventional Hubble SHO palette, the answer was a mix using pixelmath: R = SII G = 0.85*Ha B = 1.1*OIII + careful stretching and post processing.
