The usual way to do this would be to have several projectors around the 
edge of the dome projecting across the foyer.  Erich is right about 
projectors really not liking to be vertical unless they are designed for it.

Another approach is to use a convex mirror.  Google convex or spherical 
mirror projection.

Good luck!

Our budget would probably be under $50K and installation is approximately two years from now; however, the architects would like to know as much as possible at this time. Please note too that light levels will undoubtedly be high in the foyer (compared to a regular planetarium)
