New Active Regions In Calcium Light 15th August

The seeing conditions were slightly better for this image, resulting in finer detail being visible.  The 2 new active regions seem to have plenty of life about them, with numerous small spots and a decent amount of plage indicating there are good magnetic fields present.  There are some nice prominences visible on the limb too.  Taken with the 40mm scope at 925mm focal length with the homebrew CaK filter and the DMK31 camera.
