The '''Pipe Nebula''' (also known as Barnard 59, 65–67, and 78) is a dark [nebula](/source/nebula) in the [Ophiuchus constellation](/source/Ophiuchus) and a part of the [Dark Horse Nebula](/source/Dark_Horse_(astronomy)).  It is a large but readily apparent smoking pipe-shaped [dust lane](/source/dust_lane) that obscures the Milky Way star clouds behind it.  Clearly visible to the naked eye in the [Southern United States](/source/Southern_United_States) under clear dark skies, but it is best viewed with 7× [binoculars](/source/binoculars).

The nebula has two main parts: the '''Pipe Stem''' with an opacity of 6 which is composed of [Barnard 59](/source/Barnard_59), [65](/source/Barnard_65), [66](/source/Barnard_66), and [67](/source/Barnard_67) (also known as LDN 1773) 300′ x 60′ RA: 17<sup>h</sup> 21<sup>m</sup> Dec: −27° 23′; and the '''Bowl of the Pipe''' with an opacity of 5 which is composed of [Barnard 78](/source/Barnard_78) (also known as LDN 42) 200′ x 140′ RA: 17<sup>h</sup> 33<sup>m</sup> Dec: −26° 30′.
