Select the reasons why most professional telescopes are reflectors rather than refractors. A mirror can collect light more efficiently than a lens. Reflecting telescopes have shorter focal lengths than refracting telescopes. It is easier to make a large reflecting telescope than a large refracting telescope. Only the front surface of a mirror has to have a precise shape. Mirrors allow for chromatic aberration. A lens has to be supported only around its edges.
