Hi Peter. I expect getting funding for repairs has been impacted by being able to stick a planetarium on your phone or pc for free, even though it's nowhere near the same thing.
Even so, Brisbane Planetarium has recently replaced their Zeiss projector with some new type. I imagine the digital world has consigned many Zeiss projetors to the scrapyard.
I saw one in action at the Science Museum in London in the early seventies. I remember it quite vividly. One of those wow moments.
I thought Neil deGrasse Tyson's words at the end of that article were quite poignant.
