How would Galileo (in his time) convince people of the accuracy of his telescope?

How things look through a telescope is not evidence to convince people to switch to the Copernican model unless people believe exactly what they see? Galileo could have fiddled with the device so that people see an image he wants them to see. How did he convince people that his instrument was so accurate that it was worth the paradigm shift to move to the Copernican model? Surely some strong indicative reasoning is required there that did not exist yet?

You should try reading his short text “The Starry Messenger” in which he instructs the reader on how to build his device, describes what he sees and posits about the heavenly body, and then asks the reader to confirm and continue his work.
