The Pelican Nebula

IC 5070 and IC 5067, known as the Pelican Nebula, comprise a region of ionized hydrogen gas about 1800 light years away in the constellation Cygnus. The glowing hydrogen in this emission nebula resembles a pelican, hence its name.

Artistic Whimsy

In 2005 I imaged the Pelican with a telescope and camera having a smaller field of view that didn't show the entire head. I was struck by how a small region of the neck resembles an erupting volcano.

I opened the monochrome hydrogen-alpha image in Photoshop, rotated it, cropped it, and colored it reddish-orange. The region is outlined in yellow in the left image below, and the right image shows the resulting "volcano." You can see the full-size image here.
