CaK Full Disk 22nd June

The sun is very quiet at the moment, with little visible even in CaK wavelengths.  There is a small patch of plage in southern polar regions associated with cycle 25.  Cycle 24 has still not fully departed and there are still a few patches of plage on the equator.  This full disk was taken with the 100mm Tal refractor at f10 with the homebrew CaK filter and the FLIR Grasshopper 3 ICX916M camera.  Looking at the image full size it is possible to see the inverse granulation that is typified at Calcium wavelengths.
