Description

The Cave Nebula (Caldwell 9, Sh2-155) is a diffuse emission nebula within a larger nebula complex that includes a reflection nebula, and dark nebula. This deep-sky object is located in the constellation Cepheus and lies roughly 2,400 light-years from Earth.

Sharpless 155 is an ionized H II region, where new stars are being born. Small telescopes will have a tough time revealing the faint structure of the Cave Nebula through the eyepiece, but astrophotography can uncover the beautiful color and interstellar details of this nebula.
