S5346 in CaK 4th July

S5346 is the innocuous name given to what is probably currently the most active region on the solar surface, a brighter patch of plage I was initially hopeful that it might develop into an active region, but alas no, not even any signs of any mores , certainly when I have been observing it.  Taken with the ED80 at 60mm aperture, 1500mm focal length with the homebrew CaK filter and the PGR Chameleon 3 USB3 camera.
