NGC 6914 Nebulae is about 6000 ly away, toward Cygnus & the plane of our Galaxy. The view spans nearly 50 ly. UV radiation from the massive/ hot/ young stars of Cygnus OB2 ionize the region's atomic hydrogen gas, producing a characteristic red glow as protons & electrons recombine. Embedded Cygnus OB2 stars also provide the blue starlight reflected by the dusty clouds.
Cygnus crowded with stars and gas clouds, is also home to the dark, obscuring Northern Coal Sack Nebula, extending from Deneb (top center) toward the bottom center of the view. The reddish glow of NGC 7000, the North America Nebula, and IC 5070, the Pelican Nebula (upper left) and many other nebulae and star clusters are identifiable throughout the wide field. Deneb itself is the alpha star of Cygnus and is also found in 2 asterisms - the Northern Cross and the Summer Triangle.
The Cygnus Loop - Hidden within the Veil Nebula The Cygnus Loop, 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 visible light. Radio, infrared and X-ray images reveal the complete loop. The visual portion of the Cygnus Loop is known as the Veil Nebula (also called the Cirrus Nebula or the Filamentary Nebula).
