HINT: Eyepieces enlarge the (not directly visible) picture of the telescope’s prime focus. The less the eyepiece’s focal lengths is , the stronger is the magnification. So various eyepieces are needed to reach different magnifications. Begin every observation with a low magnification (20mm eyepiece).
