The sun at CaK wavelengths looks fantastic when there is alot of activity, and today was no exception. Must make a point of taking more of these images!

This was taken with the 70mm frac @ f10, homemade Baader/Coronado hybrid CaK filter and DMK31 camera. This is a result of 6 panes assembled in Imerge.
