IC1396_Bi-Colour_28-8-2019

I’ve done this one before but thought I would give it another go and collect more data. Not totally happy as the data was not obtained under the best condition with some high level cloud and some of the data was so bad I had to scrap it. As a consequence I had to limit my sharpening (using a mask) to only the brighter and more detailed areas.

 

IC 1396A also commonly known as the “Elephant Trunk Nebula” is a star forming region some 2,400 Light Years from earth. The bright rim is the surface of the dense cloud that is being illuminated and ionized by a bright, massive star. The Nebula is now thought to containing several very young stars less than 100,000 yr old.
