This image is a panorama of the Cepheus Flare molecular cloud complex in the constellation Cepheus located some 1200 light-years away. North is to the bottom and East to the right. The Iris Nebula lies on the left side of the image and it’s a bright reflection nebula surrounded by inmense clouds of dust that absorb the light coming from the stars behind them. Although the Iris nebula is also known as NGC 7023, this designation actually refers to the cluster within the nebula, while the correct designation for the nebula should be LBN 487. At the right side of the image, separated 1 degree to the east of the Iris nebula, lies the faint reflection nebula designated as vdB 141 or Sh2-136, also known as the Ghost Nebula due its spooky appearance and to several human-like figures with arms raised.
