Is Stellarium only for desktop computers?
No. Stellarium is best known as free open-source desktop planetarium software for Windows, macOS, and Linux, but there are also web and mobile versions.
Can Stellarium control a telescope?

Why do beginners use Stellarium before buying a star atlas?
It gives a live visual sky map with constellations, planets, deep-sky objects, and horizon orientation. That makes it easier to learn where Jupiter, Orion, the Pleiades, or the Milky Way should appear before going outside.
