Closing in on Decayed Active Regions - 8th August

Transparency was great this morning alas the seeing had other ideas, and many gigabytes of data were shot in order to get one half decent image.  This active region that first showed itself in June has all but gone now, but there is still a small area of crackling plage, the dark area is not a sunspot but a small surging filament, it was gone minutes later.  Taken with the Airylab HaT with 0.7x reducer and the Daystar Quark and the IMX 249 camera to get this image.
