Discs for the planetarium

I want to give my son a home planetarium. But it is sold without discs in the kit. Therefore, I need to look for them on sale. Which company is better to take them?

Planetarium disks are sold separately from the device itself. You can buy these discs online. You must buy discs from trusted companies. I take Sega Homestar Flux Discs https://astronomix.info/planetarium-discs.html Son likes Disk for planetarium Segatoys Earth and Moon the most. I think this activity is good for the child.
