IC1396 and Elephant’s Trunk Nebula

IC1396

After a OTA’s collimation…

9 x 600 sec. with Baader 7nm H-alpha filter, Artemis 11002, Losmandy Titan mount and the CDK .  All the process done with PixInsight 1.5.2. Needs more exposition, obviusly.. 😉 to increase de SNR.

From Wikipedia

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. (In the Figure above, the massive star is just to top of the image.) 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.
