IC5146 Cocoon Nebula
Reprocessed some data from 2008. This image of the Cocoon was taken through a telescope and CCD camera that I helped develop, and it was one of those nights were everything was cooperating and the seeing was good. I really like the unique color of this one. It often has a magenta look. Most of the red is hydrogen emission so it ought to look more red – but there’s also a lot of reflection and dark nebula which is scattering and obstructing some of the light.
