NGC 7023 or Iris Nebula is a wonderful example of an open star cluster associated with a reflection nebula. It is located in Cepheus, about 3.5 degrees southwest of β Cep (Alfirk).
Visually, NGC 7023 is a fairly bright, irregularly-shaped reflection nebula surrounding a 7th magnitude star (HD 200775) . NGC 7023 lies in a region of the Milky Way darkened by dust, within which the nebula is embedded.
NGC 7023 is about 6 light-years across, and 1,300 light-years away. Within the Iris, dusty nebular material surrounds a massive, hot, young star in its formative years.
Imaged in December 2024 over three nights at the Turismo Astronómico complex in Los Coloraos, Gorafe, Spain using the Esprit 100ED telescope and ASI 2600 MC Pro camera through a UV/IR cut filter.
