Cave Nebula sh2-155 Widefield


Recommended Posts

I love this target. I had never shot it using a wide field setup. Nebulae and star color match perfectly in this frame.


The Cave Nebula, Sh2-155 or Caldwell 9, is a dim and very diffuse bright nebula within a larger nebula complex containing emission, reflection, and dark nebulosity. It is located in the constellation Cepheus.
