CaK Full Disk 22nd March

It's been a while since I did any CaK imaging, but clear blue skies certainly helped, so, I decided to use the 100mm Tal refractor stopped down to 80mm to give me a focal ratio of f12.5.  The small region of activity in the centre of the disk seems to have sported a pair of pores on and off througout the day.
