AR12045 CaK 24th April

When the seeing allows, to me, CaK shots taken closeup have a view that almost reminds me of cauliflower florets.  The suns surface at this wavelength is turbulent and bubbling with magnetic froth.  This shot was taken with the 100mm at f16 with the DMk31 camera and the homebrew Cak filter used in conjunction with a Lunt solar wedge.
