How would you market for Telescope in 1750, when no one knows about orbits, moon etc ?
I was sort of busted
You have to start with the familiar. Say, "I have a novel instrument for spotting wolves among the trees." Thus, the customer will identify the telescope with need, and its novelty won't alienate, scare, or intimidate. Then, expand the horizons (no pun intended)). Allow the customer to "discover" the heavens as you marvel at his wit!
