Sitting in Cepheus not far from the Iris Nebula a network of Lynds Bright and dark objects (LBN & LDN) can be found. This picture shows part of LBN468 which contains LDN 1147, 1152, 1155, 1157, and 1158.

It also contains a small fan-like structure HH215 (slightly right and above the center of the picture), also known as Gyulbudaghian’s Nebula, discovered by Armenian astronomer Armen Gyulbudaghian at Byurakan Observatory in 1977.

This small feature is most likely the most interesting as it is a variable nebula (reflection nebulae that change in brightness because of changes in their star) much like Hubbles variable nebula.

The nebula is a jet being fired from the variable protostar PV Cephei, and the nebula changes both brightness and shape in relation to the activity of the protostar.

This intriguing picture was taken by Patrick Gilliland from Worcestershire, UK.
