Description

More info and images, please use a link under the image above.

I published the original photo of Sharpless 132 at November 11 but only in mapped colors. In this version, the narrowband channels are combined so, that the resulting image is as close as possible to a visual spectrum of human eye. Red is the dominating color since the ionized hydrogen, H-alpha, is the strongest emission line and it's emitting deep red light. Blue hues are coming from the emission of an ionized oxygen, O-III.
