Chromosphere on The Limb In Calcium Light 4th February

Not really a lot going on on in this image taken in Calcium light of the north eastern limb of our star taken with the 80mm scope at 2000mm focal length with the PGR CH3 and 2x2 binning.  What is does show is the 'hairy' limb of the sun, or the chromosphere in profile, sometimes called the spicule layer in Ha images.  With a quieter sun now upon us this is something I want to focus on for animations with a high temporal cadence in the months ahead in this years solar season.
