WebFeb 2, 2024 · A reflecting telescope is primarily made up of a mirror that bounces off the light onto a smaller focus area. A refracting telescope, on the other hand, focuses light from one end to another using lens. Refracting telescopes were big in the old world because they were easy to produce with the available technology of that time. WebA refracting telescope basically looks like a tube with a support structure to rotate it in different directions. A refracting telescope suffers from several problems. The aberration of lenses causes the image to be blurred. Also, as the lenses become thicker for larger lenses, more light is absorbed, making faint stars more difficult to observe. iphone 6s plus back camera price in pakistan
