This doesn't have a lot to do with your shutter question, but I saw, while
aimlessly trolling the internet a few weeks ago, a dome a guy made from 2"
thick Styrofoam sheet and then stucco'd. Each section was glued up from
triangles to make a fairly decent looking geodesic dome. If I ever did it I
would go with a fiberglass shell over the foam

Subject: [AZ-Observing] Dome Design Question
Probably a lot of you know there are two manufacturers of metal professional
type domes: Ash Dome and Observadome.
Does anyone know of the merits of the two types of designs of the bottom
shutter? For Ash Domes the bottom shutter swings out and down. For
Observadome the bottom shutter is composed of two sections that slide to the
side. Which is the better design? It seems the two sections that slide to
the side would act as wind sails during observing and cause the dome to
start to rotate during a strong wind. It also seems the two sections stuck
out to the side could also cause some air turbulence, depending on the
direction of the wind. I am not planning on buying either dome, but the
Observadome I have heard is significantly more expensive.
