Ha Full Disk - 25th September

Not a huge amount happening on the disk today, a few active regions, and interesting a southern polar crown in the form of a filament - indicative of the phase we are in with the solar cycle.  Proms looked great through the eyepiece though.  Taken with a 50mm Lunt etalon on a 40mm f10 scope with the PGR Chameleon 3 camera.
