AR12648 in CaK Light 9th April

Despite being designated an active region this area isn't really more than a patch of plage, and other than a few bright points has nothing that really corresponds with any sunspots.  Seeing conditions were falling off rapidly when I took this image, but by taking a number of avi files I was able to select the best on.  Lots of fine detail when clicked and viewed full size.  This was taken with the 80mm scope, home brew CaK filter and a pair of stacked 2x barlows.  The camera used was the PGR Chameleon 3.
