AR12121 CaK Closeup 27th July

Sunday was a day of clouds and clear spells, unfortunately there tended to be a lot more cloud than blue skies, however after getting a set of images with the 40mm scope I decided to get out the 80mm scope and try a few CaK closeups.  I shot numerous avis as the seeing was very temperamental at the best, in between the clouds, however this image of ar12121 came out very nicely.  It was taken at 1750mm focal length or f22, which seems to be a nice f ratio for CaK imaging,.  As usual with the DMK31 camera.
