A classic process for a classic target, one of the most beautiful and accessible nebula.
I tried to reveal all the complexity on the nebular gases.
It was a difficult object on my old location because theri max altitude is 53º and it was poorly visible. Now in Montsec it's still at 53º max but with clear horizon it was possible to add close to 20 hours of end integration.
"The cluster and nebula lie at a distance of some 5,000 light-years from Earth and measure roughly 130 light years in diameter. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses."
