This rendering of NGC 6357 uses extracted emission lines mapped to their approximate true colors for the RGB foundation, and a luminance channel equals L + 2*Ha_Line. The structural detail primarily comes from the L channel with the processing of the RGB correlating the colors with the structures.

(The title for this image comes from the common name for this object: “The Lobster Nebula.” Well, maybe before the detail was enhanced, it looked like a lobster? I must say, if it’s already cooked, the colors look lobsterish.)

An agressively colored artistic version appears as image B.
