The bright blue reflection nebula in this image (Van den Bergh 152, Cederblad 201) sits at the end of a long, curved dark nebula (Barnard 175). This complex is known as 'Wolf's Cave' nebula. The name derives from the German astronomer Max Wolf (1863 – 1932), based at the University of Heidelberg and described in several references as a 'pioneer in astrophotography'. Wolf believed that the complex looked like a cave, hence it became known as 'Wolf's Cave'.
Wolf's Cave is located around 1,400 light years away in the constellation of Cepheus.
The complex was photographed between 25 and 29 September 2019 from a remote imaging rig that is jointly owned and operated by Barry Wilson and me.
