Orion Nebula M42 (HaR- HaRGB)

Finally got half an hour of green data to finish a colour version. This uses H-alpha and Red combined as layers in GIMP to make a Red channel that is also used as Luminance, a la Robert Gendler method; but I'm experimenting really. Some unsharp mask but no noise reduction.
