Russell Croman Astrophotography  



The Veil Nebula Complex
in Hydrogen-alpha

About This Photograph

The Veil Nebula is what remains of a star that exploded thousands of years ago. It is located some 2,500 light years from Earth in the constellation of Cygnus, the Swan. Expanding sheets and filaments of hydrogen gas stretch across roughly 100 light years of interstellar space. In our sky, the Veil is huge � nearly four full-moon widths across. It is quite faint, and in this image a special filter was used to isolate light emitted by hydrogen, suppressing star light and man-made light pollution to let the detail of the nebula shine through.
