Sh 2-129 (also known as the Flying Bat Nebula), is a large emission nebula and H II region located in the constellation Cepheus. It is part of the Cepheus molecular cloud complex and belongs to the Cep OB2 association.[1][2][3][4] Reflection nebula vdB 140 can be seen near Sh 2-129.[5][6]
Within Sh 2-129 lies a bipolar outflow nebula named Ou 4 (also known as Squid Nebula).[7] The central star of Ou4 is believed to be the massive triple star system named HD 202214 (O9.5IV).[8]
