Not Designed for Immediate Observation at All Angles

The eyepiece is angled at 45 degrees, allowing for comfortable and casual stargazing—but not instant viewing from every position.

Recommended Stable Setup

For the BT81S-A optical tube, we recommend combining it with the HF2 fork mount and a ladder-type table with a free-stop mechanism, along with the highly rigid SXG-HAL130 tripod. This setup provides excellent stability for smooth and reliable observations.

Eyepiece Part

The field of sight held by hand is high quality! The model with ED lenses is the flagship of Vixen vibration canceller binoculars.

The highest of the ATERA series of vibration canceller binoculars comes equipped with ED lenses of high performance. It achieves a sharp and detailed viewing field that deserves the top-of-the-line model.

The image stabilization is so powerful that you get a stable sight in the field of view at high 16x magnification while holding it by hand. It is a special experience that you will enjoy viewing objects far away as if they are near to you.

The lightest vibration-canceller binoculars with 422 g (as of November 2017 by our company survey). It is lightweight binoculars equipped with vibration-canceller mechanism. Extremely stable field of view can be obtained even with hands thanks to the powerful vibration-canceller effect. You can observe everything in detail such as the shine of the bird's eyes and the pattern of the feathers and enjoy the live feeling as watching nearby.

Features

The incorporated vibration-canceller mechanism assures very stable image

Vibration by hands makes it often difficult to see cearly objects particularly at high magnification. ATERA H12x30 incorporates a vibration-canceller mechanism with a 2-axis gimbal control image stabilization mechanism. With a strong correction effect of vibration correction angle ± 3 degrees (up, down, left and right), a stable field of view can be obtained even at a high magnification of 12 times. Since micro vibration is also cancelled, it outperforms in observing details such as the shine of bird's eyes and the pattern of feathers. Also, if you observe a star, you can observe up to the darkest star as much as 1st grade than ordinary, which can not be seen with blurring.

Light422g design allows operating by single hand

The 422g light weight as binoculars equipped with vibration cancelling mechanism. You do not feel tired even using for a long time.

Stamina 12 hours duration with AAA batteries

Two AAA batteries are used for power supply. Since it is easy to obtain anywhere, it is safe to observe in the field and live in remote areas.Thanks to the stamina design of operation time around 12 hours (using a new alkaline dry battery at 20 ° C), you can focus on observation without worrying about battery consumption.Auto power off function which automatically turns off the power after 5 minutes elapses prevents wasteful battery drain.

Clear visibility by three coatings

By applying fully multi coating with anti-reflection multilayered coat on the entire lens surface, the phase coat on the prism that reduces halation and dramatically increases resolution, and a high reflection coat that increases the brightness of the image, stray light and loss of light intensity are thoroughly eliminated for an extreme clarity in the field of view.

Ergonomically desinged for excellent operability

A gentle rounded form fitting to a small hands, a focus ring that can be turned smoothly with light touch by single finger, a universal design that does not choose dominant hands, locating a battery space away from finger-touch area, all designed for holding comfort without stress. Considering loss of parts in a dark place such as a concert venue, we designed battery lid integrated.

Fashionable but simple design

Simple and smooth form gentle to hands, light beige color coordinated. It is a full-fledged mechanicics incorporating vibration-canceller mechanism, neutral design easy to coordinate to various fashion. An elegant and restless gloss feeling directs fashionable casually.

Mini-toto included

It comes with a mini tote bag type case. With a purse straw, the strap that tends to get in the way is also stored entirely. It fits neatly in the bag.
