Wolf's Cave, Dark Shark and Rotten Fish Mosaic

The Wolf's Cave Nebula [left] gets it's name from the German astronomer
Max Wolf (1863 – 1932), who believed that the complex looked like a cave, hence it became known as 'Wolf's Cave'. Max Wolf's assistant, August Kopff, photographically discovered the complex structure on October 21, 1908. At the centre is the blue reflection nebula, Cederblad 201. The extended dark nebula is cataloged as Barnhard 175. Together,
they are known as Van den Bergh 152.

To the lower right is the ancient planetary nebula Dengel-Hartl 5. The red filaments, extending across the image, are part of the huge supernova remnant SNR 110.3+11.3.

The Dark Shark Nebula [centre] (aka LDN 1235) is a dark nebula about 650 lights years away. Dark dust like that featured here is somewhat like cigarette smoke and created in the cool atmospheres of giant stars.

The Rotten Fish Nebula [right] (aka LDN 1251) is a dark nebula about
1000 light years away from Earth.
