Ha Full Disk 26th April

There was lots to see on our star in Ha wavelengths today despite a lack of spots visible on white light.  There seems to be lots of filaments held aloft above the suns disk today by magnetic fields.  In addition there was a fine selection of proms visible too.  This image was taken with the coronado DS40 at f16 with the DMK31 camera to make a four pane mosaic that was assembled in  Adobe photoshop.
