Cak Full Disk - 25th September

The seeing conditions were awful on sunday afternoon were awful in the unstable air following the passage of a cold front, but at least they offered clear skies, and, with the seeming distinct lack of good weather lately you have to make the most of every opportunity.  The disk was surprisingly blank in CaK light, with a area of place passing towards and over the western limb, and a small active region with some small spots just off mid disk.  Taken with the homebrew CaK filter, 40mm scope at ~500mm focal length and the PGR Chameleon 3 camera.
