Active Regions Closeup In CaK - 10th september

They aren't the largest of active regions, but they are still active never the less, and the seeing conditions were favourable when I took this image with the 60mm ED scope at 1900mm focal length with the homebrew CaK filter and the PGR Blackfly IMX249 GigE camera.  The large pixels of this camera work well at these longer focal lengths in CaK.
