AR12324 & AR12325 - Turbulent Magnetic Froth in CaK - 19th april

Energetic active regions look absolutely fantastic in CaK wavelengths, and these are no exception.  There is tons of detail in and around the spots, and the seeing must have been fairly decent as the penumbral fibrils are starting to resolve.  Taken with the Ed60, homebrew CaK filter and the Imaging Source DMK31 camera.
