Remarks:

The largest Nikon Monarch binocular with 56mm objective lenses comes in two versions, a 20x and a 16x. They are light, but well built and more compact than most other 16x or 20x instruments. Upper middle class performance for a middle class price; good stray-light suppression, an acceptable amount of CA, decent sharpness and contrast. With the 20x model, you can separate Saturns’s ring from the planet body in good seeing conditions. Newer 20×70 or 20×80 binoculars may give a slightly brighter image and even better sharpness, but they are all clearly larger and heavier.
