IC 1396 is a large emission nebula and star forming region in Cepheus with a low surface brightness. It is over 100 light-years across and about 2,400 light-years away. It is energized by the bright, bluish central multiple star called HD 206267.

The nebula is comprised of gas and dust with an embedded scattering of hot stars. The most imaged feature in IC 1396 is the Elephant's Trunk nebula, a star forming region within the main nebula.

The brightest star (38,000 Lsol) in the frame is mu Cephei. It is a red supergiant star with a diameter larger than the orbit of Saturn and is one of the largest stars we know of. Also called Herschel's Garnet Star, mu Cephei is a variable star that changes in magnitude from 3.4 to 5.1 over a period of approximately 730 days.
