AR12648 in Ha - 9th April

The seeing was pretty reasonable first thing this morning, with the solar scintillation monitor recording a steady ~1.5 arc second seeing until about 10.30am before the quality started to fall away pretty rapidly.  It was nice to see the live view so steady on the laptop screen.  This little active region is essentially just plage now, with no sunspots visible, but there were a few bright points and a small filament connecting the magnetic field lines.  I took this image with the 203mm Airyab HaT at 5600mm focal length with a double stacked Daystar Quark and a PGR GigE IMX249 Blackfly camera along with the Daystar Interference Eliminator to tame some Newtons Rings.
