The emission gas nebula NGC 6960 is part of the large Cirrus Nebula or Veil Nebula,  a gaseous structure  resulting from a Supernova event about 8000 years ago in the constellation Cygnus. The picture below shows NGC 6960, the so-called “Western Veil” with bright star 52 Cyg (4.2 mag).

Located at about 3 degrees distance are the nebula  NGC 6992, 6995 and IC 1340  the so-called “Eastern Veil”. 

The Cirrus Nebula was discovered by Wilhelm Herschel in 1784, has a diameter of 3 deg or 150 light-years located at a distance of 2400 light-years. The pictures show the nebula in H-alpha (grey scale) and a combined image using data from H-alpha and O[III] filters.
