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.
