Oldest U.S. Planetarium Projector Found & Recovered — 3 Comments

    • They exist, but my impression of them is that they are not that portable. A planetarium in my town has one. But it has its own van, etc. to haul it around. A simpler option that works fairly well is a good computer, projector, and reasonably large screen — and then use the Stellarium program, which is very nice and free. Yes, it is only on a wall, not a dome, but a portable planetarium will be a far cry from the real sky, too.
