This wispy nebula is the result of a supernova that occurred roughly 7000 years ago in the constellation Cygnus. This is a small portion of the large structure called the Cygnus loop. I’ve always been a big fan on these ghostly looking stellar formations.
Ya it’s not visibly this color to human eyes. But coloring wavelengths in post processing creates this.
Unfortunately most objects you look at through a telescope are black and white, the rods in our eyes that detect low light can’t see color. My wife was completely disappointed the first time she saw the Orion nebula through my telescope. It was super clear,but she thought she would see the same colors as the pictures.
It’s all a matter of personal preference. I like when the colorization is less saturated and closer to how we perceive the light.
