PDF-Calculating the Magnification of a Telescope

32 A telescope consists of an objective mirror or lens and an eyepiece The role of the eyepiece is to change the angle A of the rays from the objective as they enter the eye As the figure shows.

His little telescope was poorer than even a cheap modern amateur telescope, but what he observed in the heavens rocked the very foundations of Aristotle's universe and the theological-philosophical worldview that it supported. It is said that what Galileo saw was so disturbing for some officials of the Church that they refused to even look through his telescope; they reasoned that the Devil was capable of making anything appear in the telescope, so it was best not to look through it.
