Sh 2-140, a beautiful H ii region that lies on the southeast edge of Lynds 2304 — a dark nebula. Also pictured is the star cluster IC 1396 (also known as Trumpler 37), which, in turn, is situated near the edge of the Cepheus bubble. The whole lot, including the famous Elephant’s Trunk nebula, can be found about 3,000 light-years from Earth in the constellation of Cepheus.
