A little known cluster and
nebula in the Milky Way region of Cepheus. IC 1396 is large
in size, covering approximately 3 degrees of the sky just southeast
of Alderamin, the brightest star in Cepheus. In fact, it's
one of the largest emission nebula in the sky, about 6 times wider
than our full moon. The large, bright
star in this photo is the Garnet Star, Mu Cephei, a red variable
star. This star varies between 3.4 and 5.1 magnitude over
a 730 day period. Several
dark nebula permeate IC 1396 including Barnard 160,
the larger of the dark nebula on the right side as shown here. Perhaps
the most spectacular feature is van den Bergh 142 commonly called the "elephant trunk".

I managed to process much of it out but come color shift remains.
Still, a very pleasing shot!
