SWAROVSKI ATX 65 Telescope Set Angled View 25-60x65

Objective Diameter

The objective diameter determines the amount of light that enters the optics. Thus, it is crucial for performance, especially in twilight. The larger the objective diameter, the more light enters through the objective. The darker the environment, the larger the objective diameter should be. Pay attention to the exact product designation, as the number after the x indicates the objective diameter in millimeters. If a device has the addition 10x42, for example, it has an objective with a diameter of 42mm.

Variable Magnification

With variable magnification, you can flexibly adjust the magnification within a certain range. In contrast to fixed magnification, it is possible to zoom from the lower value to the higher value. However, as the magnification increases, the field of view, that is, the image section, becomes smaller. Pay attention to the exact product designation, as the number before the x indicates the magnification. In the case of 30-70x95, it is a device with 30 to 70 times magnification.

Field of View

The field of view refers to the size of the image section that can be seen through the optics. The specification is given either in meters (width) at a distance of 1000 meters (m/1000m) or in angular measurement (degrees). The higher the magnification, the smaller the field of view. Binoculars have a large field of view, meaning you can survey a large area. Telescopes have a higher magnification, which significantly reduces the field of view, but more details are visible.

Weight

The weight indicates how heavy or light the device (in grams) is. Planning to be on foot a lot? Then you should pay attention to lightweight equipment.
