CaK Full Disk - 4th Decmeber

The sun was low in the sky this afternoon, and was a waiting game for it to pass between the gaps in the trees so that I could image it.  AR12516 is a nice active region, that while not strongly active is active none the less.  It would have been nice to be able to get a close up of this area, but, the seeing was not playing.  This shot was taken with the 40mm scope at ~500mm focal length with the homebrew CaK filter and the PGR Chameleon 3 USB3 camera.
