IC 1396 is a Hydrogen alpha rich region in the constellation Cepheus. It contains the more widely-known nebula IC 1396A, the Elephant's Trunk (right center), which is a concentration of gas and dust that is recently thought to be an area of star formation. The two stars in the dark patch in the middle are older, however. The nebula's shape is caused by ionization and compression from stellar wind of the young stars it contains, pushing outward.

While the region is not that difficult to process in PixInsight (expect for noise and sheer volume of stars), it did require a good amount of capture time and could have used more as it is somewhat dim and requires an IR-sensing camera such as a modded DSLR or CCD.
