It’s that time of year when Cygnus rises high over head and displays a multitude of nebulous treasure.  This mosaic is only a portion of the Cygnus constellation but represents a large patch of sky almost 9 x 9 degrees.  This is only a test framing as I create a game plan for a summer long imaging project.  For a sense of scale, I have included a gibbous moon which was not part of the original image as well as a full scale crop of the Crescent Nebula, bottom right, to show the full size scale of the original 83 megapixel image.
