The Delta Optical Extreme 15x70 ED model is probably the most perfect of the large observation binoculars in our offer. This powerful optical instrument is made very solidly and using the latest optical technologies.

We have high-quality multi-layer FMC coatings that cover all lens elements and, perhaps most importantly, lenses made of very low dispersion ED glass with a diameter of 70 mm, collecting twice as much light as the lenses of classic binoculars with a diameter of 50 mm. ED glass eliminates chromatic aberration and increases the overall image sharpness.

The optical quality of the Extreme 15x70 ED binoculars is incomparable to the quality of cheap, popular binoculars with similar parameters. The image is sharp throughout the entire field of view, which, in the absence of aberrations, means that all contours are perceived by the observer as very distinct, and small details that are not available in lower-class equipment are visible. These are binoculars intended for above-average applications, so in addition to great optics, they also have excellent mechanical workmanship.

The Extreme 15x70 ED model is very resistant to temperature differences and can be used in a wide temperature range from -40° to +70 °C. The massive housing withstands all shocks and impacts during transport and use. Delta Optical Extreme 15x70 ED is perfect as equipment for landscape observations, observation decks and nature use. It will provide good magnification while maintaining quite high image brightness. Another attraction for observers will be the unusually large field of view.

The Extreme 15x70 ED binoculars are also an ideal instrument for observing airplanes at cruising altitudes. Quite high magnification and great image detail will allow you to easily recognize the type of machine and airline. However, these binoculars are, above all, excellent equipment for astronomical observations. It is perfect for observing bright nebular objects, comets, or large parts of the Milky Way. The stars visible in the field of view will be point-like, and in the absence of chromatic aberration they will retain their natural colors. Thanks to the presence of multi-layer anti-reflection coatings of the FMC type, we will avoid reflections when observing objects near the Moon. The binocular glasses have built-in 1.25" standard filter threads, so you can use nebular or polarizing filters.
