From Wikipedia: "The
Ghost Nebula (designated Sh2-136, VdB 141) is a reflection nebula
located in the constellation Cepheus. It lies near the cluster NGC
7023.
Looking at the adjacent image, the nebula's name is easily
understood. The Ghost Nebula is referred to as a globule (catalogued
CB230) and over 2 light-years across.
There are several stars embedded, whose reflected light make the nebula appear a yellowish-brown colour."
