Description

The Cave Nebula is an emission nebula with reflection and dark nebula surrounding. It lies in the constellation of Cepheus and is reported to be about 2,400 light years from Earth. Sh2-155 (it's official designation from the Sharpless catalog in 1959) was first noted as a “galactic emission nebula” in the Cepheus molecular cloud. Patrick Moore popularized the common name we give this nebula, “Cave Nebula”, and likely due to photographic images that show this nebula’s curved arc of emission nebulosity resembling the mouth of a cave.

Although not one of my better images, this was taken during a period when I was testing some equipment and decided to take some Ha data along the way.
