AR12585 with the 127mm Scope - 11th September

I love the furry texture of the plasma in the chromosphere in this limb image, there is active regions buried away beneath it, but they are difficult to see in this image taken with the Daystar Quark with it's transmission profile modified to have steeper sides and reduced transmission in the wings and shoulders to reduce continuum leakage.  This is taken with the 127mm Meade AR5 refractor and the PGR Blackfly GigE IMX249 camera.
