Active Regions Departing in CaK - 14th May

The seeing really was awful with a howling jet stream right over head, I was even struggling with the 60mm at 1050mm focal length.  Still, it frames these active regions as they pass towards the solar limb.  Taken with the homebrew CaK filter and the PGR Chameleon (IMX265) camera.
