The binoculars can be used with the sextant to give a better view of the horizon. The right eye will also see some of the horizon to give approximately sqrt2 i.e. about 1.4 times more light to be interpreted by the visual system. A small increase in light intensity can give a disproportionately large increase in contrast.
