CaK Full Disk 28th June

There was a worry only 24 hours ago the sun would be nearly blank as the big active region departed, fortunately another has rounded the eastern limb, and potentially there is a region developing mid disk.  Taken with the 40mm scope at 650mm focal length with the homebrew CaK filter and the PGR Blackfly GigE IMX249 camera.
