IC1396 Elephant Trunk Nebula

 IC1396 Elephant Trunk Nebula by Thomas Kerns of Beluga Lake Observaory

Object: IC1396 Elephant Trunk Nebula
Description The Elephant's Trunk nebula is a concentration of interstellar gas and dust in the star cluster IC 1396 and ionized gas region located in the constellation Cepheus about 2,400 light years away from Earth[1]. The piece of the nebula shown here is the dark, dense globule IC 1396A; it is commonly called the Elephant Trunk nebula because of its appearance at visible wavelengths, where it is a dark patch with a bright, sinuous rim. The bright rim is the surface of the dense cloud that is being illuminated and ionized by a very bright, massive star that is just to the west of IC 1396A. The entire IC 1396 region is ionized by the massive star, except for dense globules that can protect themselves from the star's harsh ultraviolet rays.

Exposure
Info:
6.75 hours total exposure time (27x15 min).
Compare this to my previous attempt at this object. This version shows more detail, and tighter start, likely due to the faster scope, and using an APO refractor, as opposed to an SCT telescope
