Binoculars and monoculars / telescopes are primarily for magnifying distant objects. Often they are compact binoculars and portable. Binoculars and telescopes are hand held so a steady hand can be needed to use them.
Magnification for the telescopes and binoculars range from 8x to 80x, with some providing variable zoom ability. Binoculars and monoculars are generally listed with their magnification level and main lens size - larger lenses collect more light, and generally give a brighter image.
