NGC6604 is an open cluster associated with nebulosity. It is located not far from my favorite Eagle nebula in constellation Serpens and it’s 5500 light-years far from the Earth. Since this deep space object is not that high on the skies, I rather used narrow band filters, because this part of the skies is strongly influenced by the light pollution, which is coming from the nearest town. First picture is processed in “fake” Hubble color palette, the second one should more or less look like in “true” color.
