Managed a few quick avi's and snapshots at lunch today quickly stacked in Registax 5 and coloured in Picasa. There was a large looping Prominence and although faint managed to at least get some hint of its structure.The snapshots are single frame snaps using the GSTAREX video cameras auto occulting function which effectively darkens the disc so the Prominences stand out more. I'm still experimenting with this .
