Another one that you need to learn. ... The largest refracting telescope ever built was the Yerkes Observatory, built in 1890 and had a diameter on $\quantity{100}{cm}$, which is tiny compared to some of the largest reflecting telescopes currently in use. A refracting telescope (also called a refractor) is a type of optical telescope that uses a lens as its objective to form an image (also referred to a dioptric telescope). The refracting telescope design was originally used in spyglasses and astronomical telescopes but is also used for long-focus camera lenses. Although large refracting telescopes were very popular in the second half of the 19th century, for most research purposes, the refracting telescope has been superseded by the r… list of paramedical courses in gujarat
