would be available by now using the spherical mirror. In
many ways it turns out to be an ideal application since it
avoids the extreme angles and hence focus issues across
parts of the dome experienced with most single projectors
and the spherical mirror approach. Unfortunately unlike the
single mirror installations that can often be created
without any particular expertise or system installer, the
two projector system would require more care to get optimal
alignment and edge blending. I had a chance some weeks ago
to work on a multiple projector spherical mirror system but
there wasn't enough in-dome testing time to complete it.
As it happens, multiple projectors ad spherical mirrors has
already been done but not for a traditional dome, see

E&S and considerably more expensive than the proposed
