Stock photo description

The Cocoon Nebula, cataloged as IC5146, is a beautiful nebula located about 4,000 light years away toward the constellation of Cygnus. Inside the Cocoon is a newly developing open cluster of stars. It is a star forming region that contains three of the major types of nebulosities: emission, reflection, and absorption. These three types of gas clouds are responsible for the red, blue, and black regions. Speculation based on recent measurements holds that the massive star in the center opened a hole in an existing molecular cloud through which much of the glowing material flows. The same star, which formed about 100,000 years ago, now provides the energy source for much of the emitted and reflected light from this nebula.

Image taken with a Canon EOS 20Da camera in prime focus of a professional reflector-telescope at 1290mm f/5.1. Exposure time is 75 minutes !

This is a very deep and real image, so the "noise" in background is no noise, these are very very dim stars again. The image is not overprocessed and sharp. See the spikes on the very bright stars.
