The  eastern  Veil  Nebula,  NGC 6992,  in  Cygnus

 NGC 6992 is at the eastern side of the Veil complex of nebulae. North is right in this image. It is sometimes called the Network Nebula because of the fine strands of intertwined gas clouds. The Veil is a supernova remnant and consists of gases blasted off an exploding star and now expanding through space. The luminescence of the gases is caused by heating due to the high-velocity shock wave.  The western Veil, NGC 6960, and eastern Veil, NGC 6992, form a circle, the Cygnus Loop, around the location of the original supernova. The two semicircles are separated by a third, unnumbered component, Pickering's Triangular Nebula.  The western portion of the Veil is shown here.

   An  H-alpha image of the eastern portion of the Veil nebula. Considerable wispy detail can be seen in spite of high clouds that were present.
