AR12152 In CaK Light 31st August

I took a number of video files to get this image on sunday afternoon as the seeing conditions were not great and I was pushing it using 80mm of aperture and 1750mm of focal length with the DMK31 camera, but, the whole principle of lucky imaging is that if you take enough images one of them will always be the best and will hopefully be acceptable.  I like the detail recorded in the penumbra of the main spot and the thin light bridge that crosses the umbra.
