Astronomical Telescope SV202 8X32/10x42/10x50 ED Binoculars...

Feature:

1.Extra-Low Dispersion ED Glass reduces chromatic aberration which causes color fringing and produces a cleaner and brighter image than standard binoculars
2.High quality Magnesium alloy body
3.Experience unparalleled resolution; contrast and color fidelity; no ghosting; blurring or focus issues. 4.Phase-corrected coatings High-refractive-index prisms produce sharp; sharp; high-resolution images; and multi-coated lenses provide brightness and vivid HD colors.
5.These telescopes are ideal for indoor or outdoor activities such as concerts; hiking; driving; watching wildlife and landscapes.
6.Waterproof and anti-fog; in order to withstand the harshest outdoor environments; these binoculars are O-ring sealed and nitrogen purged to make them completely waterproof; protecting them from moisture and preventing any form of moisture or dust from entering the system.
7.Designed for wildlife enthusiasts; binoculars optimize viewing comfort and make it easy to position the torsion rubber eyecups and knurls on the focus ring for easy natural adjustment.
8.Fully multi-coating on all air to glass surfaces helps reduce the amount of light that is randomly reflected and scattered within the binoculars; resulting in brighter; clearer; less blurry and higher contrast images for you.

ED(Extra-low Dispersion) glass is built in SV202 Binocular. ED glass has this unique characteristic and when combined with other glasses minimizes the effects of the secondary spectrum. Comparing to achromatic lenses; and ED glass reduces chromatic aberration to a remarkable degree. So if you would like to observe in low light conditions; such as at dawn or dusk and it is better to use an ED glass Binocular.

BAK4 has a high refractive index and lower critical angle than other materials; which means it transmits light better with less light being lost due to internal reflectionsuch as from internal bubbles trapped during the manufacturing process.

Fully Multi-Coated Glass means multiple coatings on all lens surfaces. And all air-to-glass surfaces are anti-reflective multi-layer coated. Super multi-coated lenses are typical of high-end optics.

100% waterproof internals to handle the most extreme weather conditions; ensuring you can watch uninterrupted views.

Whether you wear glasses or not; you can find the comfortable observation position by adjusting the eyecups.

This SV202 binocular is of low density (about 1.8g/cm3 magnesium alloy; high impact load capacity and high quality magnesium alloy body. So you don\'t have to worry about breaking it outdoors.

The diopter adjustment is a control knob on your binocular. It is designed to let you compensate for differences between your own two eyes. Once you set the diopter; then the two barrels should stay in proper relation. From then on you can focus just by turning the central focusing knob.
