Ha Full Disk - 26th March

The sun looked nice in Ha wavelengths today; the proms may not have been large, but there was a lovely emerging active region with rapidly developing spots, and also a large number of small but delicate filaments across the disk.  High cloud and haze was a real pain throughout todays imaging session, but definitely better than being clouded out!  Taken with the DS PST at 400mm focal length with the PGR Chameleon 3 camera.  I need to grease the tuning ring on the PST as is becoming quite dry and stiff in its action, making it quite difficult to fine tune the scope.
