In the following category you will find a discussion and offer of night hunting binoculars and more. First of all, we should ask ourselves what are the characteristics of night-viewing binoculars and for whom they are intended. We define each binocular by three basic parameters: magnification, lens diameter and field of view. In the case of night binoculars, the latter is the least important, but it should be remembered that a large field of view improves viewing comfort not only in conditions of lower light transmission, but also during the day. The magnification is responsible for the multiple approximation of the target we are viewing, and the objective lens collects light, giving brightness and clarity to the image. Dividing the diameter of the lens and the magnification size by each other, we get the so-called exit pupil. Night vision binoculars usually have the following parameters: 7x50, 8x56 or 9x63. What do they have in common? When you divide them by each other, you get a value oscillating around 7 millimeters, which gives a similar value to that to which human pupils dilate at night. Binoculars intended for hunting or observing the night sky should not have less than the mentioned seven millimeters of the exit pupil, because any value below will make our eye , "collect" less light, and when observing in low-light conditions, any loss of light reflects negatively on the brightness of the image.
However, there is an exception to this rule - our eye also ages as we age, and night hunting binoculars can be useful even in 8x40 or 10x50 parameters! Why? Well, the older a person is, the lower the ability of his eyes to dilate the pupil. The maximum pupil diameter of the human eye is then 5 mm. This gives older hunters the opportunity to choose smaller binoculars, which translates into a reduction in the weight of equipment carried. Many binocular manufacturers offer binoculars dedicated to hunters with parameters rather associated with hiking or daytime observation, but by understanding the concept of the exit pupil, it turns out that we don't need a night hunting binocular weighing more than a kilogram for every hunt. The easiest way to choose the right binoculars for our age and activity is to take a photograph of our own face in a completely dark room with a ruler applied to the eye. After measuring our pupil, we will get the value we should follow when choosing our new night-vision binoculars.
As you may have already guessed, night vision binoculars are more for hunters. What about other users? Binoculars with the parameters described above will be great for astronomy lovers, as they will be perfect as a handy instrument for locating galaxies. We can also find objects that we are unable to see with the naked eye. To make looking through them reasonably comfortable, pay attention to the magnification, which should be between 7-10 times. Larger magnifications, of course, offer a more detailed image, but they also generate more vibration and destabilization of the image - keeping such binoculars stable in your hands is quite problematic, and here the best solution will be to use a tripod. If you are looking for night hunting binoculars, which with their parameters will provide the best possible image even during dark nights, pay attention to our range of binoculars from companies such as Steiner or Bushnell. These are manufacturers with many years of experience in building optical devices, and the solutions they offer are improving every year, becoming a model for the competition. Also, if you are an amateur observer of the night sky, you are sure to find something for you in the category below. We wish you a fruitful search for your new binoculars!
