The scaffolding design accommodates the Go-Vex™ mirror and is basically a stripped down version of the Newtonian™2 projection case. It would be used in a clean environment where the Go-Frame™ system would be basically fixed. There are two model. The most basic Go-Frame has the projector situated in front of the mirror, projecting directly on the spherical mirror surface.
Note: Product image of a working model (by Paul Bourke), shows that many people will opt to use the Newtonian™2 projection system inside their fixed domes as the case can be closed after use, protecting the mirror.
