A lot is going on in this picture with almost no patch of dark sky visible in this view. This field encompasses most of the LBN 749 structure – a large nebula from Lynds catalog. It is situated in the constellation Perseus, close to the bright star Atik (you can see its bright halo in the top left corner). By the colors, it looks to have dust and reflection as well as emission . It is given as an HII emission region in Simbad. It is in the faintest LBN class 6. There are multiple embedded dark nebulae – LDN 1468, Barnard 3, and other darks (from Dobashi, TGU, and PGCC). Barnard 3 is a dusty, gassy region of the galaxy about a thousand light years away where young stars are lighting up their neighborhood. Toward the left center is a small reflection nebula GN 03.39.8.
