CaK Full Disk 4th July

Taken with the ED80 at 60mm and 600mm focal length, this is a 2 pane mosaic of our sun taken in CaK light with the homebrew CaK filter and the PGR Chameleon 3 USB3 camera.  This shows very well just how quiet our star is becoming as we head towards solar minimum in a few years time.
