Description

The Crescent Nebula is an emission nebula about 5,000 light years away in the consellation Cygnus. It's the result of the stellar wind from one star colliding with slower moving wind from a second star. The result is a shell and two shock waves, one moving outward and one moving inward. This was shot in narrowband using Ha and Oiii filters with RGB filters for the stars.
