Explanation:
Detailed explanation-1: -Refracting telescopes were noted for their use in astronomy as well as for terrestrial viewing. Many early discoveries of the Solar System were made with singlet refractors. The use of refracting telescopic optics are ubiquitous in photography, and are also used in Earth orbit.
Detailed explanation-2: -Reflecting telescopes use mirrors while refracting telescopes use lenses. Refracting telescopes require a much purer material than reflecting telescopes. Reflecting telescopes can be made much larger than refracting telescopes. Reflecting telescopes suffer less from aberrations than refracting telescopes.
