On this page I collect my observations of the galactic emission nebula M 17, called Omega or Swan Nebula, in the constellation Sagittarius.
M 17 (NGC 6618) is a galactic emission nebula in the Sagittarius constellation, which, according to Stoyan, is by many observers counted among the best nebulae of this type. The name Swan Nebula describes its form in a reversing telescope, but the name Omega Nebula, which dates back to William Herrschel, seems to be the more common one.
