Swarovski 17-40×56 ATC – Angled Spotting Scope


Burnt orange scope in stock

The Swarovski ATC 17-40×56 Angled Spotting Scope in Burnt Orange or Green, delivers premium optics in a highly portable form for extended backcountry tours and will fit conveniently into your backpack.



Small dimensions, outstanding optics: Thanks to its length of 258 mm (10.2 in), the ATC spotting scope with angled view will fit in any backpack. A weight of just 970 g (34.2 oz) makes it a top choice for tours in rough terrain and remote areas. The clever half shell makes it easier to position on a surface without a tripod and allows unimpeded turning of the focusing and zoom wheel at all times. In combination with the VPA, the ATC is ideal for digiscoping. The carrying strap adds the perfect finishing touch.


The objective lens diameter specifies how much light can enter the optics. This makes it a key factor in an instrument’s performance, for example, in twilight. The bigger the objective lens diameter, the more light the objective lens can capture. The darker the surroundings, the larger the objective lens diameter needs to be. Check the precise product name as the number after the ‘x’ specifies the objective lens diameter in millimeters. For example, a device with the suffix 10×42 has an objective lens with a diameter of 42 mm.


Variable magnification makes it possible to adjust the magnification flexibly within a specific range. In contrast to fixed magnification, it allows you to zoom from the lower value to the higher value. However, as the magnification increases, the field of view, i.e. the image section, becomes smaller. Check the precise product name as the number in front of the ‘x’ specifies the magnification. For example, 30-70×95 is a device with a variable magnification from 30x to 70x.


The field of view describes the size of the image section that can be seen through the optics. This is specified either in meters (width) at a distance of 1000 meters (m/1000m), or feet (width) at a distance of 1000 yards (ft/1000 yds), or as an angle (degrees). The higher the magnification, the smaller the field of view.Binoculars have a large field of view, which means you can see a wide area. Spotting scopes have a higher magnification, which makes the field of view much smaller, but you can see more detail.


The weight specifies how heavy or light the device is (in grams or ounces). Do you intend to do a lot of walking? Lightweight equipment is a priority in this case.
