Bresser Spezial Astro 20x80 Binoculars without tripod

Porro prism. Magnification: 20x. Objective lens diameter: 80mm

Porro

Prisms of the binoculars adjust the image orientation projected by the objective

The higher the magnification of the binoculars is, the larger the object will be, but the narrower the field of view (FOV) and the darker the image

The larger the aperture is, the more light there will be that enters the optical tube and the image will be brighter, although a larger aperture will increase the size of the binoculars
