This is IC 1396 located in the constellation Cepheus about 2,400 light years away from Earth, and the area marked by arrows is known as the Elephant's Trunk Nebula, a concentration of active, star-forming, interstellar gas and dust within the much larger ionized gas region. The bright rim around the Elephant's Trunk is the surface of a dense cloud that is being illuminated and ionized by a very bright, massive star. The imaging, done remotely last night on T14, a 106 mm refractor at the Mayhill, NM, iTelescope.net site, was done with narrow band (Hydrogen, Sulfur and Oxygen) filters to mitigate a very bright near full moon.
