C9 / Sh 2-155 The Cave Nebula - telescope processed image. Located 2,400 light-years away in Cepheus, the Cave Nebula is a 35-light-year-wide H II region where radiation from hot stars triggers new star formation.

C9 / Sh 2-155 The Cave Nebula - unprocessed image. It earned its name from the dark, cave-like hollow at its center, which is actually a dense cloud of dust and gas silhouetted against a bright ionized rim.

Good Sunday morning. Waking up early to see the results of the s50’s planned observations from last night. Went back to see #C9 / #sh2155 #TheCaveNebula without the onboard light pollution filter. The Moon and Sky Light filter was still used. #seestar #S50 #space #astronomy #amateur

A stunning image of the Cave Nebula (Sh2-155) in the Cepheus constellation. This vibrant skyscape showcases the nebula's reddish emission region, blue reflection nebulae, and the bright red fleck of Herbig-Haro 168, all set against a backdrop of countless stars within the Milky Way galaxy. The image spans approximately two full moons and reveals intricate details of star formation within a massive molecular cloud located 2,400 light-years away.

A breathtaking image of the Cave Nebula (Sh2-155), a stellar nursery located 2,400 light-years away in the Cepheus constellation. The vibrant reddish glow of ionized hydrogen gas is illuminated by the radiation from nearby hot, young stars, creating a stunning cosmic landscape. This region shows active star formation at the edge of the Cepheus B molecular cloud, spanning over 10 light-years across.
