On this page I collect my observations of the galactic emission and reflection nebulae NGC 6960/6992/5, called Cirrus or Veil Nebula in the constellation Cygnus/Swan. All in all, it is about the Cygnus Loop, a supernova remnant.

 

Introduction

The galactic emission and reflection nebula NGC 6960/6992/5, called Cirrus or Veil Nebula, in the constellation Cygnus/Swan is a compound of the galactic nebulae NGC 6960 and NGC 6992/5. According to Stoyan, a labyrinth of weak nebulae and fine filaments is distributed over a larger area (2.5° x 3.5°), but this can only to recognized under good observation conditions. And obviously, I did not have these in summer / autumn 2016 ... But in August 2020, I was able to catch at least a glimpse of NGC 6960 and of NGC 6995 with the eVscope, although all this is far too large for the eVscope's field of view. The Vespera shows already larger sections of both nebulae, but you cannot capture the whole cirrus nebula in a mosaic.

NGC 6960 is also called Western Veil Nebula), whereas NGC 6992/5 is also called Eastern Veil Nebula. Together, they are the remnant of a supernova that happened about 8,000 years ago. Various parts of the remnant have different NGC and IC numbers. For example, the objects NGC 6960, NGC 6974, NGC 6979, NGC 6992, NGC 6995 (inofficially called Bat Nebula) and IC 1340 all belong to the same structure called Cygnus Loop:

Wikipedia: The Cygnus Loop (radio source W78, or Sharpless 103) is a large supernova remnant (SNR) in the constellation Cygnus, an emission nebula measuring nearly 3° across. Some arcs of the loop, known collectively as the Veil Nebula or Cirrus Nebula, emit in the visible electromagnetic range. Radio, infrared, and X-ray images reveal the complete loop.

Note: NGC 6960/6992/5 (Cirrus or Veil Nebula), M 1 (Crab Nebula), and IC 443 (Jellyfish Nebula) are the only supernova remnants that I have observed so far.
