AR12759 Deparing in CaK 9th April

This interesting active region is no more than a region of plage as it approaches the departing limb, but has put on quite a pleasing show over the past 10 days or so.  Nice to see cycle 25 activity slowly hotting up.  Taken with the Skywatcher ED80 stopped down to 60mm with the Revelation ED 3x barlow lens, the home brew CaK filter and the FLIR IMX174 chipped camera.
