CaK Full Disk 10th May

Nice to see some active regions and their associated white plage visible on the sun.  There seems to have been a slight uptick in solar activity in recent weeks going against the longer downward trend as we head towards solar minimum.  Taken with the 40mm f10 scope somewhere around f13 with the homebrew CaK filter and the PGR Chameleon 3 USB3 camera.
