(meteorobs) looking for links to camera domes 7" and larger

When I was in High School (1967) I made clear plastic domes in Shop Class,
by adapting a small Pressure Cooker. The pot can be cut away to reduce it to
a ring. By replacing the steam vent in the lid with pressure hose fitting
the lid becomes a pressure dome. The pot which has been reduced to a ring is
clamped over a Plexiglas sheet. Placing the clamped sheet in a temperature
controlled oven allowed pressure to be applied to the assembly and blow a
fresh new dome in just a few minutes.

I am searching for any links to clear camera domes that would be larger than
normal all-sky size, for example 7" diameter or larger. I tried Surplus Shed
but their domes appear to have imperfections so am looking for higher
research grade quality.

Thank you in advance.
