A photo of the "Omega Nebula (M17)"1also known as the Swan or Lobster nebula owing to it's shape is visible in the constellation Sagittarius. The various colors of the nebula are fluorescence of hydrogen, nitrogen, oxygen and sulphur atoms excited by bright stars within. I imaged the nebula through a 110 ed refractor using a Meade dsi lll camera from St John's on September 17, 2011.
