Ngc 7023
NGC 7023 (sometimes known as the Iris Nebula or with the abbreviation C 4) is a diffuse nebula visible in the boreal constellation of Cepheus. It was discovered by William Herschel in 1794.
NGC 7023 is a reflection nebula, ie it reflects the light of some nearby stars; probably the main star responsible for its illumination is precisely the seventh magnitude star, cataloged as HD 200775, which would be enveloped by the nebula, together with other less bright stars born from its dust and which form the open cluster. The nebula is probably about 1400 light years from us and measures about 6 al. It is probably part of the vast Cepheus Molecular Cloud Complex.
Distance from Earth: 1,300 light years
