Graphic showing the assembly of narrowband grayscale data used to create an LRGB narrowband false color image of NCG 7380, also known as the Wizard Nebula.

 

Luminance channel is Halpha data.

R=[SII] data

G=Halpha data

B=[OIII] data

 

Graphic shows the atomic transitions corresponding to the different channels that are used to build up the composite RGB mosaic. Each grayscale image of narrowband data is colorized and used to build the full color composite. Athough [SII] and Halpha are both in the red part of the visible spectrum, they are mapped to red and green respectively.

 

This nebula is a star-forming region located in the outer arm of our galaxy. Note the bubble of ionized gas surrounding the star at center left.
