Great shots and what an ingenious idea to use exposed B&W film.
Though I'm not completely sure, I though this was not the proper protection! At least I know that looking through a CD to the sun isn't the correct protection against the sun's rays. Check this on the site of Fred Espenak (?) who's a eclipse hunter and work for NASA. There are to many rumors and false claims about proper protection for looking at a solar eclipse. Oh, and to Steve: be careful pointing a big lens at the sun (although 420mm is maybe ok) and only putting the filter in the filter box. The light is already bend when it reaches the filter and it is possible that it burn through the filter! Especially with telescopes this is *NOT* the way to look at the sun, put the filter on the opening of the lens. Since this creates really expensive filters, Mylar foil is used...
