The Elephant Trunk Nebula

IC 1396, HaOIII

October 30, 2016

This is my first HaOIII bicolor, and I don’t really know how to feel. I think it looks ok, but there is very little OIII data here because it is quite faint. A better test will be the veil nebula, which I and currently finishing up.

The Elephant Trunk (as IC 1396 is called) is a large emission nebula in Cepheus.
