Fan mentioned atmosphere. That's one. I think another is the law of diminishing light. Light only travels so far, and the North Star is closer than we have been told. The firmament might only be around 100 miles up, give or take.
On your question though, the North Star can be seen past the equator around 23 degrees or so, which is impossible on a ball earth.
