Active Regions in Calcium Light - 20th May

There was only a chance for observing the sun very briefly this morning before the heavy showers started to roll in, even then I was cloud dodging and only managed a couple of images in Calcium light.  This close up taken with the 40mm scope at ~900mm focal length used the homebrew CaK filter and the PGR Chameleon 3 camera.  This is the third consecutive rotation for this family of active regions that sit either side of the solar equator.
