Description

M20, The Trifid Nebula is an H II region located in Sagittarius. It is a good example of 3 kinds of nebulae; an emission nebula seen as the red region of ionized hydrogen gas, a reflection nebula seen here as the blue region reflecting the light of the central star, and a dark nebula seen as the dark regions separating the region into its characteristic "lobes".

This image was captured using a monochrome camera and using red, green and blue filters to create a color image, and the colors are further enhanced in the red and blue regions by incorporating the narrowband Hydrogen Alpha and Oxygen III filters. 11 hours total integration time.
