【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

Effective diameter: 40mm Magnification: 2.3x Actual field of view: 28° Maximum dimensions: 123mmx40mmx50mm Weight: 255g Focusing mechanism: IF compatible eye width: 52mm to 73mm Infinity focusable diopter: ＞ -6 diopter Standard accessories: Neck strap, 2-way carrying case WideBino28 is a unique opera glass that shows an amazing wide field of view of 28°. Most constellations fit in one field of view, and even stars that are 1 to 2 magnitudes fainter than the naked eye can be clearly seen, giving you a unique visual experience that makes you feel as if your naked eye has been doped. This is a reprinted and improved version of the legendary product ``Wide Bino,'' which was sold in the 1990s and received rave reviews from many people who love starry skies as a completely new type of ``stargazing glasses.'' The unique optical design remains the same, but the optical performance, coating, and specifications of each part have all been updated, and accessories such as a neck strap and 2-way carrying case that are convenient for observation have also been enhanced. ＜Optical system＞ Galilean opera glasses generally have a narrow field of view, and to improve this shortcoming it is necessary to use an objective lens with an extremely small F number (F2 or less), but with general achromatic lenses, the image quality is greatly affected by the effects of strong aberrations.
It is not very practical as it will be disturbed. WideBino28 is a revolutionary ultra-wide-field opera glass that uses a uniquely designed meniscus objective lens with two elements in two groups and a cylindrical eyepiece with two elements in one group to suppress each aberration to an extremely low level and successfully focus a good image from the center of the field of view to the periphery. Furthermore, the latest version has broadband multi-coating applied to the entire surface of the lens to maximize transmittance, and thorough internal treatment to suppress the occurrence of flare, resulting in significantly improved contrast and sharpness compared to the old product. The color balance within the field of view is also very natural, with no visual field coloration seen in older products. ＜Body Structure & Accessories＞ The compact and lightweight body has a maximum length of approximately 12cm and a weight of 255g, with most parts made of metal. Focusing uses a separate IF method for left and right. A rubber ring has been added to the eyecup part, which was exposed metal in the old product, so the area around the eyes will not get cold even when used in winter. Front and rear caps are also included to keep the lens surface clean at all times. Furthermore, the latest version adds strap holders to both ends of the main body, and a neck strap convenient for observation is also included as standard. Can be worn in two ways: worn over the shoulder or worn on a belt.
A 2-way carrying case that allows you to carry Idovino is also included as standard. ＜Overall Suitability＞ The wide field of view of 28 degrees provides an overwhelming sense of openness that could never be experienced with conventional opera glasses, making them the best suited for stargazing. It is now possible to bring a single constellation within its field of view, and it can also recognize stars that are 1 to 2 magnitudes fainter than the limit of magnitude seen by the naked eye, so it can be said to be the only equipment that can perform the feat of checking out nebulae and star clusters scattered throughout the constellation while viewing the entire constellation. In particular, when you look at the star-filled region around the Milky Way, the beauty and sense of realism you get is indescribable, and once you see it, you become addicted. Please come and experience a unique way of seeing that you have never seen before, as if ``the range you see with your naked eye is much closer to you''.
