The engineers of the American optical company Celestron built their brainchild without using a focus system in its design. This function is given directly to the human eye and is carried out due to accommodation — the adaptation of vision to the objects under consideration at different distances.
Great coverage
The world through the eyepieces of the binoculars looks clear and sharp without the influence of parasitic effects (such as chromatic aberration) on the image. Inverting prisms of the Perro type have a large diameter, which provides a large field of view of the binoculars — at a distance of 1 km, it captures in its lenses the area, the largest distance between two points of which is 139 m.
Minimalism
The binoculars are made in a minimalist style. To get started, just bring it to your eyes and adjust the eyepieces for yourself, spreading them to the required distance. For those who have poor eyesight, diopter correction is provided in the range of ±5 D. The body of the optical device stands out for its excellent ergonomics, secure grip in the hands and the presence of a tripod mount. In addition, it is dust and moisture resistant.
High sharpness
The lenses of the binoculars do not have any antireflection coating, therefore, despite the large diameter of the exit pupil, the image in low light conditions does not shine with high detail. When using binoculars of this type, it should also be taken into account that the eyes are subject to increased stress. In order to minimize it, it is not recommended to use the device for long-term observations. But for a short look at active sporting events or at wild animals and birds, binoculars are the best fit, which is facilitated by excellent sharpness throughout the field of view.
tourist orientation
Celestron UpClose 8x40 AutoFocus, among other things, is appreciated among tourists. Especially those who are prone to outdoor activities. It will help you quickly assess the situation around, quickly find a place to sleep or see which way this or that path will lead.
