Sundays Active Regions - 8th May

Sundays active regions looked very dramatic and detailed in this shot taken with the Skywatcher ED80 and Daystar Quark in conjunction with a naked PST etalon in the output telecentric beam to reduce continuum leakage in the wings.  This setup is very successful in producing very high contrast images.  Taken with the PGR Blackfly GigE IMX249 camera.
