Fujinon FMT SX-2 10x70 binocular

Among the brightest astronomy binoculars on the market, the Fujinon FMT 10x70 provides outstanding light transmission of over 95% and a wide field of view without distortion thanks to its aplanatic lenses. The fields of application of the Fujinon FMT SX-2 10x70 prismatic can be both for lunar observation and large star fields, nebulae, etc. such as for monitoring forests, ports and airports, nature, etc.

It is equipped with flat field eyepieces (field flattener), avoiding chromatic aberration, astigmatism and distortion peripheral. In this way we will obtain point stars without deformation with an impressive color fidelity. and it is blackened to avoid ghost images. Additionally, all optical surfaces, including high-index BaK-4 prisms, are multi-layered, providing exceptionally bright, high-contrast images. Its anti-reflective optical treatments will help us avoid ghost images and we will obtain a great contrast between the black sky and the star fields. Accepts polarizing and nebular filters, as required by observation needs.

The die-cast aluminum exterior finish makes it highly resistant and shockproof. It is 100% waterproof, withstanding drastic changes in temperature and humidity. It is filled with dry nitrogen and sealed with an O-ring that prevents condensation and internal fogging of the body. The focus system is auto-focus, being able to focus from 20 meters to infinity and being able to individually adjust the diopters of both eyepieces.

Despite their 70mm diameter, the binoculars are compact and very comfortable to hold. However, the use of a tripod is recommended for long observations. The product warranty is 30 years .
