Description:
The Iris Nebula, also known as NGC 7023, is a reflection nebula located in the Cepheus constellation about 1400 light-years away from us. Reflection nebulae are clouds of gas that reflect light from nearby stars, in this case HD 200775, located in the center of the nebula, which is responsible for its distinctive blue color. The nebula is part of a larger complex of dark nebulae, which occupy almost the entire field of view and emerge, as in this case, in long-exposure photos
