Rich area of nebulosity in the centre of constellation Cygnus that includes the Crescent Nebula (aka NGC 6888) at left, and the Tulip Nebula (aka Sharpless 2-101) at right near the star Eta Cygni. The small circular red HII nebula at lower left is Sh 2-104, while the faint arc of whitish OxygenIII nebulosity below centre is the Wolf-Rayet nebula WR134. The Crescent Nebula is another Wolf-Rayet object, WR136, made of material expelled by stellar winds from a very hot central star. The long dark nebula above centre is B145, from Edward Emerson Barnards catalogue, while the mass of large dark nebulas of varying densities at right is collectively catalogued by Beverly Lynds as Lynds Dark Nebula LDN 862. The star cluster Messier 29 is just in the field at lower left. Many other minor star clusters dot the field. Photographed from southern Alberta, Canada on 16 May 2023.
