Answer to Question 1

elliptical

Answer to Question 2

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. A telescope's power is in its diameter, not its magnification, which can be adjusted by changing out an eyepiece.
