AR12599 in CaK - 9th October

Stopping the aperture down from 100mm to 80mm helped to tame the poor seeing on sunday 9th, but it is difficult to make out the penumbral fibrils, which when visible is always a indication of better conditions.  Taken with the home brew Cak filter and the PGR Chameleon 3 camera.
