IC 1396 is a stunning emission nebula located in the constellation Cepheus. The bright central star, HD 206267, ionizes the surrounding gas, causing it to glow in brilliant hues of red and blue. The nebula's distinctive shape, often referred to as the "Elephant Trunk," is created by dense columns of gas and dust that shield the nebula's interior from the ionizing radiation. The trunk of the elephant is also a site of ongoing star formation, with several young stars visible within the structure. IC 1396 is a beautiful example of the ongoing processes of stellar birth and death in our galaxy.

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.
