If you plan to photograph this, make sure you have the right filters, and also note that the filters which make it safe for your camera don't always make it safe for your eyes. You can get some info at http://www.mreclipse.com/SEphoto/SEphoto.html I haven't decided if I'll buy a good glass filter or just use a filter holder.

Also, probably best to debug all your equipment in advance, using a regular sun, before the eclipse. Getting the right length lens, etc. is kind of a pain.

(I'm borrowing a canon demo 500mm L prime for the Transit of Venus next month).
