S5346 With The Airylab HaT - 3rd July

The boffins at NASA say the face of our sun is currently blank; this is a relative term, and depending on how hard you look depends on how much you can see.  This is where the 0.2 metre Airylab HaT comes into it's own.  With a double stacked etalon the contrast was very high due to a lack of continuum leakage and as a result this un-designated region with its dark filaments and bright plage really stood out.  Taken at 5.6m focal length with the PGR Blackfly GigE IMX249 camera.  With a decline into solar minimum coming the larger apertures will continue to win out in solar observing, where the smaller scopes just don't have the resolution to view these smaller scale features of the chromosphere.
