CaK Closeup - 29th July

This image is a closeup of the region of plage that is visible in the full disk image in the post below.  Taken with the 100mm Tal100R refractor, homebrew CaK filter, Coronado 2x cemax barlow lens and FLIR GH3 IMX174 camera.  The Airylab Solar Seeing Monitor was used to get Firecapture to select only the sharpest subframes to be recorded.  I'm quite pleased with the result as is rare the seeing obliges like this for me.  It will be interesting to see how much of this plage is still visible in less than a months time when this region of our star makes a reappearance again.
