Sh2-155

 

Sh2-155 or Caldwell 9, is a dim and very diffuse bright nebula within a larger nebulacomplex containing emission, reflection, and dark nebulosity. It is located in thconstellation Cepheus.

Visually it is a difficult object, but with adequate exposure, makes a striking image. The nebula gets its name Cave Nebula from the dark lane at the eastern side abutting the brightest curve of emission nebulosity which gives the appearance of a deep cave when seen through a telescope visually.
