Description

It's all about the NGC 7538 region in the constellation Cepheus.
This region of active star formation is located about 9,100 light-years from Earth.

The picture is a result of more than 78 hours of integration time in narrow band and rgb channels.
I could say that is a more complicated target than I thought at the beginning, it was difficult to post process this image due the high dynamic range needed to reveal all the details.
