The 7x50: best choice for observing in twilight and the dark
In general a 7x50 binocular is fantastic for observing in the twilight or the night sky. Unexperienced observers very often do think there is a an electronical light amplification inside! Where does that come from? The exit pupil from a 7x50 will be 7.1 mm. This is actually the maximum size a human' s pupil can expand to. In other words: The light of the 50 mm objective lens will be concentrated to the 7 mm of the eye' s pupil without loss of light. Effectively there is really MUCH more to be seen compared to the naked eye.
