Don't put the burden of Grand Success on your shoulders. You don't need to, you're not the one who's organising this. Focus on the thing you're arguably good at (because otherwise you wouldn't have been asked): making people excited about astronomy! If I went to such an event, my expectations would be "someone smart who tells about their field of study with excitement". Aim for that. Like, how the hell do we know all those things about the Earth and about our stars? It's weird for outsiders that you can look through a tube, make some calculations and predict a friggin' eclipse.
