NGC 6871 Open Star Cluster & WR 134 Wolf-Rayet Star with a beautiful section of Nebula In Cygnus.
I really like the structure and dark nebula in this region as well.
NGC 6871 is a small, young open cluster in the constellation of Cygnus. The cluster has fewer than 50 members,
most of which are blue and white stars. It is located 5,135 light-years from Earth. NGC 6871 was born in the same
giant molecular cloud with at least six other open clusters.
WR 134 is a variable Wolf-Rayet star located around 6,000 light years away from Earth in the constellation of Cygnus,
surrounded by a faint blue bubble nebula blown by the intense radiation and fast wind from the star. It is five times the radius of the sun, but due to a temperature over 63,000 K it is 400,000 times as luminous as the Sun.
WR 134 was one of three stars in Cygnus observed in 1867 to have unusual spectra consisting of intense emission lines rather than the more normal continuum and absorption lines.
These were the first members of the class of stars that came to be called Wolf-Rayet stars (WR stars) after Charles Wolf
and Georges Rayet who discovered their unusual appearance.
WR 134 is classified as an Algol type eclipsing variable and given the designation V1769 Cygni, but the variation is not strictly periodic and brightness changes occur on timescales of hours to days.
