S5353 and Filaments - 5th July

This bit of sun on the western limb was quite interesting; subtle filaments and choppy plasma around S5353.  Taken with the Airylab HaT at 203mm aperture, 5.6 metre focal length with a Daystar Quark double stacked with a PST etalon using a PGR Blackfly GigE IMX249 camera.
