No, not madness.

Last week I was pointed in the direction of Baader AstroSolar Safety
film. Some details at

I managed to get this image using safety film on an EOS 350D with a
70-210 Sigma zoom at 210, F5.6, 1/800th:

It seems there's not much going in in Sunspot land, but there is some
limb darkening going on.

I thought it may be of interest, particularly to those of you with
something with a longer focal length who are interested in something a
little scientific - at 210, the disk is still too small for my liking.
