Cave Nebula SH2 155
Hi, I have been working on my version of the Cave Nebula in Cephus. Sh2-155 apparently goes by several designations like many other objects. I observe the extensive presence of the dark clouds and bok globules that make the shape what it is. The violent strength of the star formation areas central to the image really contrast and catch my eye. I really like the summary about SH2-155 on telescope.com for background information.
