IC 1396 is a very scattered open cluster associated with a large diffuse nebula, visible in the boreal constellation of Cepheus; it is located in a stretch of the Milky Way partially obscured by dense banks of dark nebulae, in a galactic region rich in dust and gas with associated young and hot stars.
The nebula has a roughly circular appearance: the combination of telescope and sensor used to take this image did not allow it to be taken in full, but in the image you can guess its circular shape.
The whole nebula is crossed by numerous dark spots, which on closer analysis turn out to be Bok globules, that is particularly concentrated regions of the nebula where the formation of new stars takes place.
It is therefore an H II region, and is part of a vast system of molecular clouds and OB associations called the Cepheus Cloud Complex.
A particular dark nebula that overlaps the object is also called Elephant's Trunk and is identified with the initials vdb 142.
The whole nebula complex is about 3000 light-years from the Sun.
