Departing Active Regions in Ha - 25th July

This is the only 'hi res' shot I salvaged today, with the SM90 and 2x cemax barlow, with temperatures up in the high 30's imaging wasn't really on the cards!  A few days ago this turbulent plage on the limb was a small cycle 24 active region.  The IMX174 camera was unhappy as was recording a working temperature of 62c - ouch!
