Ha Full Disk - 16th May

Today was the last day with the spell of good weather that we've been having this last week, and throughout the sun has has something on show.  Active region AR12741 is slowly but surely decaying and is unlikely to survive another rotation to return as a sunspot, possibly plage?  We'll have to see in 2 weeks time.  Taken with a Lunt 50 etalon on the ED60 f60 scope with a 2.5x barlow and the FLIR GH3 ICX916M camera.
