Thank you for the link.  I sent them a suggestion as to use of large
Plexiglas mirrors for the outboard mirrors.  Although second surface on a
less smooth substrate, they should work quite well because of the relative
size and distance (Pixels per unit area).

Sort of similar to the effect of a large format high speed film resolving as
sharp an image as a small slow speed film.
