For this one, I choose to translate the french title. In english it is better known as Cygnus Loop or Veil Nebula. I thing the french name is more poetic.
The remains of a star that exploded about ten thousand years ago. We call it a supernova remnant.
It’s a great summer classic. I never miss to go to observe it visually. It is a pleasure to stroll along the filaments, from the large lace (on the left) to the small (on the right) via the Volutes of Williamina Fleming. Sometimes when the sky is really good, I can perceive other weaker part.

Yes, they even have their nebula… I’m not telling you where the North America Nebula is or why we call it like that, it’s pretty obvious. It’s identified as NGC 7000. To its right is the Pelican Nebula, IC 5067 and IC 5070. The bird is a little harder to recognize.
These nebulae represent only part of the H-alpha complex found in the Cygnus. Ionized hydrogen is found in a large part of the constellation and even beyond.
