Description

This SHO Hubble Palette image was constructed in a slightly different manner. This is a Tone Mapped image. Normally the H-alpha channel with augmentation would act as the luminosity layer over the tone map. In this case, the O3 was twice as bright as the Ha. So the luminosity layer was a combination of H-alpha and O3, reflective of their relative strength.

Hubble Palette images usually have that nice orange-turquoise color palette. With O3 being so intense, that was not possible, and in any case would not reflect the gaseous composition of the nebula. so instead we have blight blue dominating the image.

Next we did the RGB stars and layered them onto the SHO image.
