Trifid Nebula
The Trifid Nebula is an HII region in a star-forming region in Sagittarius. Designated M20 after discovery by Charles Messier on June 5, 1764. Messier identified over 100 objects that he classified as “not” comets. An avid comet hunter, he wanted to identify and catalog objects that resembled comets but were not, in fact comets but were distractions from comet hunting.
The original data for this image was captured by astrophotographer Peter Jenkins and was offered by the telescope.live website as a “pro data set” for processing.
The data consists of 6×180 second exposures each using luminance, red, green, and blue from the Planewave CDK24 telescope at the El Sauce Observatory in Chile. I processed the raw images in my studio using Pixinsight and Photoshop.
