I've always wanted to take a stab at this.  Shot at 2800mm f/10.  Although I didnt have any cloud cover, a cold front was passing
through and I lost all but 39, 300sec subs.  The Edge 11 made a better wind sail then an OTA.  It was like taking a photo
through a back yard pool with three kits splashing around....  Pixel peepers beware, I am not responsible for any visual ailments.
