I bought a Sega Homestar home planetarium for my kids. We really enjoy looking at the stars and constellations. But the problem is that it only came with one disk. Is there nothing else I can watch?
Why not? Of course there is a possibility to buy separately disks with different educational programs. To find them you can go to a store that sells various teaching aids. In addition, you can buy Homestar classic discs here: https://astronomix.info/planetarium-discs.html There is a large selection and you can choose what you are interested in.
