A couple of months ago I was given a cool home planetarium and 2 disks for it for my birthday. I was, of course, insanely happy because I've been interested in astronomy for a long time, but in two months I've gotten bored with the two disks. And friends seemed to say that Sega Homestar has a large selection of different disks. Can you tell me where they can be found on sale?

Yes, indeed, Segatoys planetariums are probably the best devices among all analogs, because their manufacturers offer not only a high-quality device through which you can study the cosmos, but also a fairly large assortment of different discs for variety with different interesting pictures. Here is the site, which presents all this large selection of discs for planetarium astronomix.info/planetarium-discs.html (https://astronomix.info/planetarium-discs.html).
