To determine the total magnification of any object viewed under your microscope you would... Multiply the magnifying power of the eyepiece by the magnifying power of the objective Most compound light microscopes have four objective lenses with magnification of 4X, 10X, 40X, and 100X. What magnifications are available if the eyepiece magnifies 15 times?
Most commonly used magnification is a 7x, but 8x and 10x are also chosen by some mariners and boating enthusiasts. A 42 or a 50 millimeter objective lens should be used. A larger objective lens, waterproof and rubber armoring are main features to look for in a marine and boating binocular.
