Dear Diallists
I would like to share with all of you a photo gallery which is a result of
three short visits to France (Summer 2010, Summer 2011 and Autumn 2011).

The gnomon point of my sun dial is also very thin. In order to observe the
shadow point as exactly as possible, I use an old and simple trick: by
touching the gnomon-point with one of my fingers, the semishadow almost
disappears
locally and I can better observe the exact location.

A
hemispherical convex mirror mounted above a (hopefully
clear) ceiling window so that you can see, from
inside the room, the bright reflection
