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 second Go-Frame™ available is called the Go-Frame™ Plus, where the projector is behind the curved Go-Vex™ mirror and projects onto a secondary mirror which reflects to the primary mirror, much like a Newtonian™2. This setup has a smaller footprint where space is a consideration.
