Reflecting telescopes are optical instruments that use mirrors to gather and focus light from distant objects in space. The primary mirror, usually curved, collects light and reflects it to a focal point, where an eyepiece or camera can capture the image. This design allows for larger apertures, making them effective for observing faint celestial bodies. One of the most famous reflecting telescopes is the Hubble Space Telescope, which has provided stunning images and valuable data about the universe. Reflecting telescopes are popular among both amateur and professional astronomers due to their ability to produce clear images without the chromatic aberration found in some refracting telescopes.
