Elephant’s Trunk Nebula – IC1396
Elephant’s Trunk Nebula
This was a lot of shooting to get to this point, but still not the best data…. though it did process out pretty well I thought. 5 sessions using narrowband monochrome in Ha, Oiii, Sii were used and then processed through Astro Pixel Processor. The elephant has an interesting eyeball with a faint star in there if you look close enough.
