Ha Disk 2nd July

There may be no spots currently on the face of our star, but in Ha wavelengths at 656nm there were plenty of filaments to see.  I was hoping to get 2 panes to make a full disk, but this was all I could manage with the gaps that I had.  Taken with a Lunt 50 etalon at 40mm aperture at 560mm focal length withe the PGR Chameleon 3 USB3 camera.
