What is the best way, on a small mirror, to 'add'
correction to the edge? Texereau talks about using TOT,
offset...but there is so much danger of turning the edge
that it seems dangerous. I'm finishing up a 6" f/4.5, so
there is quite a bit of correction to put in, and I need to
add some at the edge.
