Lobster Nebula, M17
The Lobster Nebula is also known as the Omega or Swan Nebula. Much like constellations, everybody can see a different shape in the pattern. The nebula is an active star forming region which is partially obscured by dust clouds in the foreground which make it appear to have its shape. Because there are other stars in the foreground it gives the optical illusion that it is the red cloud which has the shape. The nebula is an “emission nebula” because the gas is glowing from the heat generated by the star formation within it.
This photograph was a 5 minute exposure taken with an SBIG ST-2000 astronomical camera through a LX-200GPS 12" reflecting telescope.
