CaK Top 30th april

No more big filaproms in CaK today - maybe that little surge on the eastern limb is indication something is on the way around the limb, hopefully so as the sun is looking rather quiet in CaK at the moment.  Taken with the 40mm at 560mm focal length with the homebrew CaK filter and DMK31 camera.
