This region of glowing hydrogen is a very compact object in constellation Cygnus in about 2000 light years distance.

What you see here has a diameter of only 2 light years. The energy source powering this nebula is a very young star in the center of this nebula currently obscured by dust and thus not visible here. The strong radiation of the star will blow the dust and glowing hydrogen away in the next thousands of years.
Stars never form alone … so this major bright star is actually part of a star cluster forming around this cloud of gas and dust. This cluster is a bit special because about 600 brown dwarfs have been detected inside. Brown dwarfs were created by the collapse of a cold molecular cloud, converting gravitational energy to heat. The mass of these objects was however not large enough, to heat up their core sufficiently to ignite nuclear fusion. So they will not become real stars. But as this cluster is currently extremely young, these objects are still hot enough to be detectable in the infrared part of the spectrum before they cool down, become completely invisible and hide for ever in the deep darkness of the universe.

I had a lot of trouble getting some sort of nice picture out of my data, because I apparently lost collimation a bit and got some sensor tilt, which I discovered to late during that night. I was so happy that my EQ6R Pro mount is finally tracking and guiding now as it should. So this picture got round stars only because I worked hard on it …

The morning after I acquired these data I started up my PC to work on the data … and Windows‘ Welcome Screen showed exactly this object, but of course the famous Hubble/Subaru image combination, which is of course by orders of magnitude more detailed than my image.
It was as if MS wanted to tell me: „Hey, we know what you did yesterday. And we show you, how your image could look like … haha“
