CaK Full Disk - 26th March

Out of all the images I took today I think my favourite is the CaK full disk, despite the haze, high cloud and contrails this came out really sharp.  The new active region was positively crackling with activity, looking noticeably brighter than the other plage regions.  Taken with the 40mm scope at 400mm focal length with the homebrew CaK filter and the PGR Chameleon 3 camera.
