The Flying Bat, Squid & Seahorse Nebulae in Cepheus

The Flying Bat, Squid & Seahorse Nebulae in Cepheus

Astrophotographer Gianni Lacroce: "Sh2-129 is a large emission nebula visible in the constellation Cepheus. It is also known as the Flying Bat Nebula. Its distance has been estimated at around 1,300 light-years. The Squid Nebula, cataloged as Ou4, is barely visible—a truly difficult subject! The image shows the faint emission from the oxygen III atom it is composed of."

"The perspective makes them appear very close, but they are very distant. To their right is the Seahorse Nebula, a dark nebula immersed in the dust of Cepheus."

The Flying Bat Nebula, also known as Sh2-129, is a faint emission nebula located in the constellation Cepheus, notable for its unique shape and association with the nearby Squid Nebula (Ou4).
