text: The light enters the tube and reflects off a curved mirror (called the primary mirror) at the other end, before bouncing back up the tube to near the top where it reflects off a smaller mirror (called the secondary mirror), which bounces the light out of a hole in the side of the telescope where you attach your eyepiece.
