Sunspots the simple way: took this picture a few minutes ago with a Lumix FZ48 at full zoom thru old eclipse glasses ... which, although made for visual observing, were still not quite dense enough for 1/2000 second at f/8 and ISO 100. Will have to experiment with other filters for the transit of Venus.
