Alpen Optics Vixen Binoculars ATERA H10x21 with stabilizer ES11499
Fewer vibrations in the field of view
Increase the visibility of object details and higher comfort
For landscape and star observations in astronomy
Ergonomically designed for excellent usability
Carrying strap and mini bag included
The ATERA H10x21 with 358 grams is one of the lightest binoculars with image stabilizer. Due to the strong vibration canceller effect, an extremely stable field of view is achieved even from the freehand. At higher magnification, you can observe everything in detail, such as reading signs and lettering, recognize the structure of bird feathers, and the ATERA is also a great companion for astronomical observations of stars. Fewer vibrations in the field of view increase the visibility of object details and the comfort of observation.
The vibration of your hands often makes it difficult to see sharp objects, especially at high magnification. ATERA H10x21 features a vibration suppression mechanism with a 2-axis gimbal-mounted image stabilization mechanism. With a strong correction effect of the vibration correction angle of ± 3 degrees (up, down, left and right), a stable field of view can be achieved even at a high magnification of 12x. Since the micro-vibrations are also eliminated, even the finest details can be seen.
Two standard AAA batteries are used for the power supply. As they are easy to get everywhere, safe operation is guaranteed even in remote areas. Thanks to a long operating time of up to 12 hours, you can concentrate on observation without having to worry about battery consumption. An automatic power-off function, which cuts off the power after 5 minutes, prevents unnecessary battery discharge.
By applying a complete multi-coating and an anti-reflection coating on all lens surfaces, the additional phase coating on the prisms, the light transmission and thus brightness of the image is drastically increased. All these features ensure low stray light and light loss and produce a particularly clear and high-contrast image. A gently rounded shape that adapts to the hands, a focus ring that can be gently rotated by lightly touching it with just one finger, a simple design, a battery compartment that is away from the operating area, all designed for ease of use. The integrated battery cover effectively protects against loss.
The ATERA is delivered with a comfortable carrying strap and a protective bag for transport.
