Exploring the possibilities with APF-R processing, here is a roll-over image
of the Sun (displaying the longest solar filament ever recorded) I took a few years ago, but shown now with and without APF-R.

Also thanks to Marcus Davies for supplying a Photoshop APF-R action which
makes tinkering with this technique a good deal easier :thumbsup:
