NGC6618 (M17) Diffuse Nebula

39. NGC6618 (M17) Diffuse Nebula
M17, otherwise called the Horseshoe or Omega nebula, lies in an extremely rich area of the Milky Way. Though this large gas cloud can be readily detected in binoculars, a 6-inch telescope is needed to see its hooked shape distinctly. With any instrument, use low power.
