30 minutes of exposure of Orion's Sword. The largest cloud, the Orion Nebula proper, also known as Messier 42, is visible to the naked eye as a pink or purplish fuzz patch in the constellation Orion. It is an active star-forming region, and from our perspective, all of the ultraviolet emissions from the young and superhot stars cause all of the surrounding hydrogen to glow red and blue, effectively creating a pinkish color. There is a smaller nebula to the lower left of the larger one, De Mairan's Nebula, or Messier 43, and one to the left, sometimes known as the "Running Man Nebula." The Running Man Nebula is actually three distinct clouds of gas (NGC 1973, NGC 1975, and NGC 1977) that are reflecting much of the starlight the young, hot stars in the region. The "Running Man" is the dark silhouette that is in between all three. The green glow in the main Orion Nebula comes from oxygen atoms that have been doubly ionized (lost two electrons). This is my best capture yet of this region of space, and also posted is my first long exposure from 2013 of this region.
