Description

One of my most complex projects so far. I shot this target on three nights using my Optolong L-Extreme duo narrowband filter and processed the Ha and Oiii channels separately to later combine them with RGB shots for the stars. Thanks to Nico Carvers excellent video "3 WAYS to edit Dual Narrowband Astrophotography!" on youtube on the "Nebula Photos" channel :-)

About the target:
The Elephant's Trunk Nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light years away from Earth. The piece of the nebula shown here is the dark, dense globule IC 1396A; it is commonly called the Elephant's Trunk nebula because of its appearance at visible light wavelengths, where there 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 (HD 206267) that is just to the east of IC 1396A.
