Description

Face spiral galaxy NGC6946 also called "Firework Galaxy" in Cepheus constellation at border with a Cygnus constellation, far approximately 25 million light year from us. The short focal length of my telescope allow me to include in the picture the beautiful cluster  NGC6939. LRGB picture unfortunately almost with the full moon.
