CaK Full Disk 14th February

Seems like it's been a while since I got some images in CaK light.  I think the truth is the clear skies have been so few and far between that when it was good I was playing around with the triple stack in Ha wavelengths.  Anyway, nice to see the sun down in the blue end of the spectrum again!  Taken with the 40mm scope at 700mm focal length with the PGR Blackfly GigE IMX249 camera and the home brew CaK filter.
