Vega, Altair, and Deneb make up the summer triangle asterism, from the constellations Lyra The Lyre, Aquila The Eagle, and Cygnus The Swan. Also visible here are Vulpecula The Fox, Sagitta The Arrow, Delphinus The Dolphin, Equuleus The Foal, and parts of Draco and Hercules. And of course the Cygnus arm of our Milky Way Galaxy.
This is my first long exposure output from my new motorized barn-door tracker, fourteen- three minute exposures stacked. Plagued by atmospheric haze, thin fog and noise from the high ambient temperature I had a difficult time processing this image.
