Comments:  This was a mild night with a low of 65, but it was mosquito heaven. The Snake Nebula (also known as Barnard 72) is a dark nebula in the Ophiuchus constellation. It is a small but readily apparent S-shaped dust lane that snakes out in front of the Milky Way star clouds from the north-north-west edge of the bowl of the Pipe Nebula. Its thickness runs between 2′ and 3′ and runs around 6′ in the north-west / south-east orientation. To the right side of the Snake Nebula is found Barnard 68. Below it are found Barnard 69, Barnard 70, and Barnard 74.
