CaK Full Disk 26th April

The time of year has arrived where for several months i'm able to observe the sun early in the morning before I leave for work; it's always a pleasant way to start the day.  This morning our star was quiet all bar a decaying active region AR12706 visible as an area of bright white plage on the disk.  A small sunspot was also visible.  Image taken with the 40mm f10 scope running around 500mm focal length with the homebrew CaK filter and the PGR Chameleon 3 camera.
