Description

The Elephant Trunk Nebula is a sinuous concentration of gas and dust within the large emission nebula known as IC1396.

I decided to take a wide field shot of this subject after noticing that the surrounding nebula contained some interesting features. This is my first Hubble palette image.

Thanks for looking.
