Ar12284 CaK 17th february

This active region really has fizzled to nothing over the past couple of days, and is now no more than a patch of plage.  Still, the sun is virtually featureless at the moment so it makes for one of the more interesting bits never the less.  Taken with the ED60 at 1500mm focal length with the homebrew CaK filter and the DMK31 camera.
