Well, there is already one "Observatory for Everyone". Of course, I'll forgive the kickstarter person for not knowing of it. It's small and it's in Lincoln, Nebraska, USA. (Full disclosure: That's where I live, too.)

"Hyde Memorial Observatory is, as far as we know, the only observatory anywhere that is: built, furnished and operated entirely by donations, devoted exclusively to public viewing, completely free of admission charge, staffed only by volunteers. Hyde is open every Saturday evening, year round." -- http://www.hydeobservatory.info/

So, I do support the new observatory, but I'd encourage folks to consider investing in the existing one.
