From SEDS.ORG:
-------------------

The diffuse nebula NGC 6960 marks the western half of a faint nebula, which is sometimes called Wreath, sometimes Loop or Network. Best known under the name Veil Nebula. More than 50,000 years ago a supernova exploded south of epsilon Cyg, close to the southern border of Cygnus. Nowadays the afterglowing gas forms this large nebula which shows a circular shape. The eastern and brighter part of this nebula got its own NGC number: NGC 6992. It is a challenge for binoculars. You need best conditions to observe it. Using a wide-angle telescope at low power will show NGC 6992.Despite its overall brightness of about mag 5, this object is only visible to the naked eye under exceptionally good viewing conditions, because its light is distributed over the object's large size.
