CaK Full Disk - 1st May

One of those first thing in the morning shots, it's that time of year!  The seeing was awful especially considering the apparently clear blue skies, still, nice to get some sun.  It never ceases to amaze me what stacking software can do with what seems like very poor data.  Taken with the 40mm f10 somewhere around 500m fl with the homebrew CaK filter and the PGR Chameleon 3 camera.
