The neighborhood of the Iris Nebula in Cepheus holds more secrets. This arrow-shaped complex is LBN 468 with lots of swirling bright and dark nebulosity.

A very interesting and small structure, resembling a tiny comet, can be found at the tip of the arrow. This is the Herbig-Haro object known as HH 215 or Gyulbudaghian's Nebula. It consists of a jet of gas streaming from the variable protostar, PV Cephei, and it varies in brightness and shape as the progenitor star brightens and darkens.

This is an LRGB composite of 24 L and 16 R, G and B exposure of 900sec each, taken at the Deep Sky West Observatory.
