CaK Full Disk 22nd July

The CaK full disk shows very well the new activity that is coming around the suns eastern limb, both with the new sunspot group and also quite a few prominences that are also visible, normally a good indication of more activity not far off.  The new filter configuration with extra out of band blocking is holding up well, and easily reveals the double limb and prominences, not normally features that are easily visible in CaK light.  The disk was taken with the 40mm scope at 700mm focal length with the DMK31 camera.
