Deep Sky Objects

Deep Sky Objects, as listed on this page, refer to galaxies and nebulae (with their associated stars). Star clusters (like the Pleiades and Hyades), are also included. Most named stars, if not surrounded by nebulae, are described in the "Special stars" section of the IAU Constellation page.
