Image Description:
This is a widefield shot of the γ Cygni (aka, Sadr) region in the constellation of Cygnus. I blew the focus on this, but the shot isn't too bad nonetheless. Of course, it's hard to tell that the focus is blown at the image scale displayed herein. <grin> A higher resolution image of this widefield shot is also available, as is a closeup of the immediate Sadr Region from last year. North is right.
