M17 - The Omega Nebula

The Omega Nebula (M17) is vast star forming region similar to the nearby Eagle Nebula (M16), imaged a few weeks ago, and the Orion Nebula (M42), imaged in January. It is named omega because parts of it resembles the Greek letter omega when looking at it through a telescope. Good eyes can spot this in a dark location on a very clear night.  It is about 5,000 light-years distance compared to 1,300 light-years for Orion.  Number 32 for the Messier Objects with an ED80.
