Am folosit in multe cazuri vederea periferica si cu binoclul, si nu mi s-a parut a fi un dezavantaj pentru binoclu fata de telescop. Link-ul de pe cloudy nights conclude la capitolul vedere periferica in favoarea binoclurilor:

"Averted Vision
This may become somewhat of a deficient point for binocular vision. It is well known thhat each individual has an optimum location for detecting low contrast objects with averted vision. The location may vary with the individual, however there are studies that show location, IIRC, about 15° off center and generally at an angle from the center of vision. It shouldn't be too hard to understand that it would be near impossible to have the image fall on the optimum location in both eyes at the same time. Hawever, all of the above tests done to predict gain in limiting magnitude are done observing stars at the 5%-10% limit of vision, meaning they are only visible 5%-10% of the time viewing and they are always observed with averted vision. So while the averted vision object image cannot fall on the optimum location in both eyes at the same instant, still the eyes see more averted vision with binocular vision than without."
