AR12320 CaK Closeup

I thought seeing as spring has officially sprung here in the UK that I would get the 100mm Tal refractor out this morning under the glorious blue skies we had, unfortunately the seeing was just not paying ball and out of over 40 movies that I took this was really the only image worth processing.  You can tell the seeing was lousy as the penumbral filaments are not resolved.  Taken with the 100mm Tal at 1750mm focal length with the homebrew CaK filter and the Imaging Source DMK31 camera.
