Description

Sh2-155 (Caldwell 9) is known as the Cave Nebula and is 2,400 light years from Earth in the constellation of Cepheus. It's a diffuse nebula approximately 70 light years in diameter belonging to a larger region of emissions nebulae, reflection nebulae, and dark dust clouds.

This was one of the last photos I took in Del Rio, TX and (like the others I've posted) it comes with an interesting story.. On this night I along with my observing partners (my doggies) played host to 2 very vocal screech owls. I'm not sure if you've heard one of these owls sound off before but it is a very eerie, blood curdling sound and I encourage you to look it up on the internet.

The first time they sounded off it was about midnight and very quiet. My dogs and I both jumped at the sound and my poor little Pomapoo (Pomeranian Poodle mix) wet himself he was so scared! Even my Lab-German Shepard mix cowered and started whimpering. For my part I took cover around the side of the building (and nearly soiled myself) as I had never heard one of these owls before and was fairly convinced that we were being haunted by some otherworldly spirit.
