reflecting telescope
Quick Summary
A reflecting telescope uses a concave mirror to gather and focus light, rather than a lens like a refracting telescope. This primary mirror, typically made of glass coated with metal like aluminum, reflects light to a focal point. This design avoids chromatic aberration, a distortion caused by lenses dispersing light by wavelength.1
Invented by Isaac Newton in 1668, reflecting telescopes have evolved with various designs like the Cassegrain and Newtonian. These instruments are crucial for observing the electromagnetic spectrum, including ultraviolet and infrared light, and have become the predominant type of large telescope used today.12

Giovanni Battista Amici…improvements in the microscope and reflecting telescope, but he also put his instruments to good use. His observations of Jupiter’s satellites and certain double stars were highly esteemed. Using an improved micrometer of his own design, he made accurate measurements of the polar and equatorial diameters of the Sun. With…
