DO Extreme 15x70 binoculars are equipment for consideration by observers of serious aspirations. We have here excellent quality FMC shells and, perhaps most importantly, ED low-dispersion lenses with a diameter of 70 mm, collecting twice as much light as the lenses of the classic 50 mm binoculars. These are special glass lenses that eliminate chromatic aberration and increase the overall sharpness of the image.
Optical quality Extreme 15x70 is incomparable to the quality of cheap, popular binoculars with similar parameters. The image is sharp in the whole field, in the absence of aberration, all contours are perceived by the observer as very expressive, and also small details are visible which can not be seen in the equipment of the lower class. It is a binocular designed for more serious applications, so in addition to excellent optics, excellent mechanical performance was also taken care of.
Extreme 15x70 is very resistant to extreme temperatures: it can withstand 40 degrees frost as well as desert heat. The robust housing withstands all shocks and impacts during transport and use. The Delta Optical Extreme 15x70 is perfect for landscape observation, observation terraces and natural use. Ensure a good magnification while maintaining a fairly bright image. The attraction for observers will also be a wide-angle picture.
Extreme 15x70 is also an ideal instrument for observing airplanes at cruising altitudes. High magnification and brilliant image detail allow you to easily recognize the type of machine and airline. However, these binoculars are above all an excellent equipment for astronomical observations. It is great for observing bright nebular objects, comets, or large fragments of the Milky Way. The stars visible in the field of view will be punctual, and in the absence of chromatic aberration will preserve their natural color. Thanks to the presence of FMC coatings, when observing objects near the moon, we avoid glare.
