Plage in Calcium Light 10th April

cak-plage-colour Emerging-region-cak-colour Conditions weren't great but I went for a closeup of this plage on the surface of the sun, the last image looks to be developing into something a bit more active. Taken with the 100mm at f40 with the home brew CaK filter and the IMX174 camera.
