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

C9 / Sh 2-155 The Cave Nebula - telescope processed image with Moon and Sky Light Filter and LP Filter. C9 / Sh 2-155, the Cave Nebula, is a beautiful star-forming region in Cepheus. It is an H II emission nebula featuring a dark, curved dust lane resembling a cave mouth.

C9 / Sh 2-155 The Cave Nebula - unprocessed image with Moon and Sky Light Filter and LP Filter. The Cave Nebula is an active stellar nursery where radiation from hot, young stars is compressing gas and dust, which triggers new star formation!

Decided to go back to #C9 / #Sh2-155 #TheCaveNebula. #seestar #S50 #space #astronomy #amateur

C 9 / Sh 2-155 The Cave Nebula - telescope processed image with Moon and Sky Light Filter. An emission nebula (H II region) in Cepheus, 2,400 light-years away. Nicknamed "The Cave Nebula" (C9) for a dark, hollow cavity sculpted by radiation from hot, young stars.

C 9 / Sh 2-155 The Cave Nebula - unprocessed image with Moon and Sky Light Filter. A hot O-type star outside the "cave" is bombarding the gas with radiation, triggering the formation of a brand new generation of stars!

Another new #nebula observation for me. Here is #C9 / #Sh2-155 #TheCaveNebula. #seestar #S50 #space #astronomy #amateur
