AR12764 in Ha 1st June


This active region following it's M-class flare burst a few days earlier is holding it's potency well, and while distinctly more quiescent than active is still sporting a spot and plasma structures.  The image was taken with the 100mm Tal100R, Airylaby 2.7x telecentric, Daystar Quark and the IMX174 camera.  This setup lets in lots of light and might be interesting to double stack with a PST etalon in the future for disk shots like this.
