CaK Full Disk 29th July

While there might appear to be not much happening in this full disk taken at Calcium wavelengths, it shows well the region of plage mid disk associated with final cycle 24 activity as a result of the active regions we had in this area in spring time earlier in the year.  The image was taken at 80mm f12.5 with the homebrew CaK filter and the FLIR GH3 ICX916M camera.
