CG30-31
CG30-31
CG30,31 is a cometary globule complex located in southern portion of the large Gum Nebula near the constellations of Vela and Puppis. Unlike the more famous nearby, cometary globule CG4, this is a complex of several globules (CG30, CG31, CG38) and dark clouds.
As well as emitting in the visible spectrum, the area contains some very strong X-Ray emissions.
Sometimes less is more - I tried mapping all LHaGB channels in PI - the result was nice but the colour was not all that varied. The Blue and Green data were very similar, so I omitted the Blue data. I just mapped the Ha to Red and the Green data to a Lime Green (0,255,0). This produced the deep Red Ha in some parts, some green in other parts and some golden yellow where the Red and Green coincide. Adding the Luminance layer in photoshop brightened and sharpened things up.
It looks more Christmassy than the Christmas Tree Nebula.
