Ha Full Disk 30th December 2019

This is my last solar image of the decade; clear skies on monday meant I was able to make the most of the small gaps in the trees to get a chance of seeing the sun.  Cycle 25 active region AR12753 is still visible as a patch of bright plage, but all sunspots have now receded.  A few small prominences and few ephemeral bright points are the only other things visible but as we move into 2020 activity is set to rise.  This image was taken with the Lunt50 etalon on the ED60 f6 scope, double stacked with a Daystar Quark, a Baader solar telecompressor was used along with the PGR camera.
