Reflecting telescopes

A reflecting telescope uses curved mirrors to gather and focus light, instead of lenses. Light from distant objects hits a large primary mirror that gathers it and reflects it to a smaller secondary mirror. This secondary mirror then directs the light to an eyepiece, where the image can be viewed or recorded. Reflecting telescopes are commonly used in astronomy because they can be made larger than lens-based telescopes, allowing for better light collection and clearer images of faint celestial objects. They also avoid issues like chromatic aberration that can affect lens telescopes.
