How applicable is this projection technology for a large fixed dome?
Fulldome projection in large and/or fixed domes is largely about a tradeoff between the resolution on the dome and the cost. The top of the line system currently consist of multiple projectors (either 2 very high end projectors in the center of the dome or 5/6/7 projectors around the rim) and come at a significant cost. The next alternative is a single (or two) lower end projectors with a fisheye lens, for more information on this see The Elumenati.Using a single projector and a spherical mirror is the lowest cost solution and it is definitely an option for fixed planetarium domes and is already being using in a number of domes worldwide. If you are interested in this then there is a network of planetariums using this technology, send me an email and I can put you in touch with the relevant people at these sites who can share their experiences.
