	Also, never look through your view-finder when trying to take
a shot of the sun even when you've mounted the neutral density filter!!
How do you line up the shot?  Simple.  With the lens cap on simply align
your camera with the sun using the shadow of your lens as a guide.  Move
your setup around until you have minimum shadow around the lens...equal
on all sides.  Kind of like a sundial.  Simple, easy, quick and SAFE.
(Remember, however, to leave your lens cap on when not shooting...no sense
asking for trouble.)
