INFO
IC 1396 spans hundreds of light years at distance of about 3000 light years in constellation Cepheus. The famous formation of glowing gases, the "Elephant's Trunk Nebula" can be seen at four o'clock position. This is an active star formation region and it has several massive young stars inside it, coursing the ionization of elements of this emission nebula.
