There could be other explanations too like their referring to maps and determining the city closest to where the star seemed to indicate. Then as documented, they went to that city and asked. The appearance of the star directly overhead afterwards, would be a bonus.
I never said just three Magi, only Magi. That would need a minimum of two Magi, or Maguses. It could have been quite a caravan with support staff too.
Stars do mean less to people quite accustomed to excellent indoor lighting. When your room is lit as well by night as it is by day, the occasion to go outside at night and observe seems less attractive. And also light pollution hides stars that used to be visible.
You haven't watched the video. The star was not directly overhead.
The gospel tells us that the rabbis in Jerusalem told them the king would be born in Bethlehem. Why speculate when the gospel tells us how the Magi found Bethlehem?
Head to the wilds of Utah (Goblin Valley would be good) to see stars as they are.
Clear air, a warm campfire and extremely low light pollution makes for a wondrous experience for city folks who have been blindered by technology.
And they were NOT at any stable; either!
