I've had a home planetarium at home for a long time now. But not so long ago I discovered that you can put special disks in this technique. I found these sega flux discs here https://astronomix.info/planetarium-discs.html Has anyone bought a product from them? I would like to understand whether it makes sense to cooperate with them or not?
I've never even heard of any planetariums. And anyway, you can go to a planetarium and see what you are interested in. But I don't see the point of keeping it at home!
