AR12529 in CaK - Final Views 19th April

Even though the sun was low and I had the focal length racked up, I was able to compensate for the reduction in exposure time and oversampling of the image by doing 2x2 binning of the pixels on the PGR Chameleon 3 (IMX265) camera.  This still gives a nice resultant image that is noticeably sharper than by not binning.  Taken with the Skywatcher ED80 stopped down to 60mm aperture with the homebrew CaK filter.
