The region around IC5070 (Pelican Nebula) in Cygnus is a favorite target for widefield astrophotography in Ha light.  The deep shadows and rifts in this nebula are caused by dust that obscures visible light emitted by ionized gas such as hydrogen.   Please click here for a high resolution image of this region taken by Russell Croman.
