Dark Nebula, Galaxy, Open cluster in Cepheus

This deep field is covered
            with tawny dust. On the left is the Seahorse nebula - Barnard
            150. You can see it is merely a denser concentration of this
            localized dust cloud. On the right are two remarkable objects,
            also immersed in the foreground dust. The galaxy NGC6946 is a
            beautiful spiral and is dimmed considerably by the dust, and
            yellowed as well. Above it is the dense cluster NGC6939 complete
            with golden and blue supergiants. So much going on here.
