Taken by Mike Borman from my back yard in Evansville, Indiana, with a Televue 102iis refractor, Coronado SM90 h-alpha filter with BF30, and Point Grey Research Grasshopper 3 camera.
While taking this image, as well as white light and CaK images, I set up a GoPro camera and created a time lapse movie of my observing session, which can be seen here:
