Sh2-80 is an irregularly shaped planetary nebula located at the western edge of the constellation Sagitta. It can be found out easily to follow 3.3 degrees NNE from ζ Aql, which is located at the northern tip of the constellation. The nebula has a diameter of less than 2 arc minutes, a brightness of 8th magnitude, and is emitting red Hα light. It is thought that Sh2-80 is formed by the released hydrogen gas from the 11th-magnitude Wolf-Rayet star (WR124) located in the center neared the end of its life.
