Which of the following items are usually seen as reasons why reflecting telescopes are more commonly used by astronomers than refracting telescopes? Select all that apply. Select one or more alternatives: Reflecting telescopes are less likely to distort images by treating different wavelengths of the light in different ways. Reflecting telescopes are easier to protect, because their mirrored surfaces are covered by glass. Reflecting telescopes are more easily pointed at specific objects. Large reflectors are easier to build than refractors. Reflecting telescopes were invented first, and have always been the primary tool of astronomers.
