Actually, astronomers are people who study the stars. Astrologers are people who believe that the stars dictate the fate of humans. There's a big difference.
That said, there was a lot of conflation of the two prior to the invention of the telescope.
Ahh I see like horoscopes and the like, though I would not know what to call it if someone saw a asteroid heading on a direct path to earth in a telescope, would that be considered astronomical or astrological event kind of seems like both Hahaha
