New Active Regions in CaK Light - 9th August

There are several active regions that have rotated round the suns eastern limb over the past couple of days, and, should give plenty to look at if clear skies remain!  Taken with the Tal at 80mm and 1400mm focal length with the homebrew CaK filter and the PGR Chameleon 3 camera.
