Description

NGC 7023 is commonly called the Iris Nebula because of its resemblance to the flower of the same name. It is a reflection nebula with the gas and dust reflecting the light of the 6.8 magnitude star in its center, SAO 19158. The thick concentration of dust in this area contributes to the reddish cast of most of the stars shining through it.

NGC 7023 lies at a distance of 1300 light years and is approximately 6 light years across.
