Answer to Question 1

False

Answer to Question 2

Because the magnifying power of a telescope, its ability to make images bigger, is the least important of the three telescopic powers. Because the amount of detail that a telescope can discern is limited generally either by its resolving power or the seeing conditions, very high magnification does not necessarily show more detail.
