CaK Full Disk 23rd December

The sun was looking nice down at the blue end of the spectrum, and this full disk taken with the 40mm scope at 700mm focal length was good in riding above the poor seeing that was prevailing with the low near solstice winter sun.  Taken with the homebrew CaK filter and the PGR Blackfly IMX249 GigE camera.
