Front 10

Why do most professional astronomers use reflecting telescopes rather than refracting telescopes?

Back 10

because mirrors are cheaper and can be made much larger than lenses.

Front 11

Two ways in which astronomers can overcome the distortion of starlight that is caused by the earth's atmosphere.

Back 11

Place a telescope in space, where there is no air to distort the telescopes "vision" & Binoculars.
