spitz a4 planetarium projector cheap or free in iowa city, iowa:
Thanks so much for posting this! I'm picking it up a week from Saturday. The current owner has tried for years to get a public center built, but needs to part with it for personal reasons. He wanted to give it to someone who actually hoped to get it up and working again, and I promised him I would try my best to do so.
I own a Starlab portable planetarium, and travel around Wisconsin with it, sharing the night sky with schools and libraries. I also worked with my astronomy club and school district (I'm a member of the school board) to build a public observatory in our school forest.
I just showed a photo of this projector to our superintendent today, and he is interested in exploring the idea of adding a planetarium to the new performing arts center we're hoping to build. I really did not have high hopes for that, but planned to get the projector anyway, just because, who wouldn't? (ok, almost everyone wouldn't!) I'm excited!
Another thing I do is refurbish old cameras. I've mentioned that here before. It makes me glad when I can get well-made things that can still work well, up and running again. An old 4x5 camera will record gigabytes worth of information on a sheet of film. No consumer digital camera can do that yet (though they do have advantages, of course).
I'm not a fan of digital planetaria. I have not been in any with the very latest technology, but those I have been in do not, in my opinion, show the pinpoint stars that older opto-mechanical projectors do. Even my lowly Starlab fools almost everyone who enters it into feeling as though they are under a real sky. They get woozy when I move the stars quickly.The Spitz A4 projector uses 40-year-old technology, but it's technology that works.
