Magnification: 20x magnification means that objects will appear 20 times closer than they are. This is great for seeing distant objects in detail, such as birds, wildlife, or celestial bodies.Objective lens diameter: 50mm refers to the diameter of the objective lens, which is the large lens at the front of the binocular. A larger diameter lens will gather more light, resulting in a brighter image, especially in low-light conditions.
