Fans and professionals of \"digiscoping\" will rightly appreciate the excellent quality of the product made directly in Japan. One of the distinctive features of the spotting scope is the large objective diameter and wide magnification range. High-quality, interchangeable ED Pentax eyepiece included. Full multi-coated illumination and BAK4 prisms provide high light transmission, contributing to a bright and clear image, even in very low light. High aperture and twilight factor indicators guarantee the possibility of observation at dusk and in inclement weather. The design is completely sealed. The housing is filled with nitrogen, which prevents condensation of vapor on the internal optical surfaces during significant temperature changes.\u003c\/p\u003e\u003cp\u003e The manufacturer of the Pentax brand values the high quality of its products, so to eliminate fakes on the market, each unit of Pentax optics is assigned a unique serial number at the manufacturer's factory, thanks to which you can identify the authenticity of the product and be sure that you have a truly original, high-quality optical device.\u003c\/p\u003e\u003cp\u003e \u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003e The large, bright 80mm objective lens has excellent light-gathering ability, making it ideal for low-light observations.\u003c\/li\u003e\u003cli\u003e \u003cstrong\u003eExtra Low Dispersion Glass\u003c\/strong\u003e (optical glass with extra low dispersion) provides perfect color image transmission and a high degree of resolution. The refractive index of the beam with low dispersion glass is extremely low and does not depend much on the frequency of light (on the spectrum). All light waves are refracted by the same angle, providing impeccable image clarity. The use of these glasses allows you to minimize such an annoying aberration as chromatism. The cost of ED glass is very high, which is why manufacturers of high-tech sports optics use it only in their premium products.\u003c\/li\u003e\u003cli\u003e \u003cstrong\u003eFully-multi-coated\u003c\/strong\u003e Full multi-coated broadband optics provide equally high light transmission across the entire visible spectrum and contribute to high contrast and color rendering in natural tones.\u003c\/li\u003e\u003cli\u003e \u003cstrong\u003eBAK4\u003c\/strong\u003e Barium crown is a special type of optical glass used to make prisms in optical instruments. This material has a lower dispersion coefficient (light scattering) than the glass used for budget models. As a result, chromatic aberration (iris at sharp transitions from dark to light) is significantly reduced. In addition, a clearly defined refractive index of light avoids vignetting (the phenomenon of cutting off the light beam at the edges), which provides a uniformly bright image throughout the field of view.\u003c\/li\u003e\u003cli\u003e \u003cstrong\u003eWaterproof\u003c\/strong\u003e The optics are sealed and protected from moisture penetration according to \u003cstrong\u003eJIS 6\u003c\/strong\u003e (Japanese Industrial Standards). Immersion in liquid to a depth of 1 meter will not harm the device and will not affect its functionality. No weather conditions are scary for such optics.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e \u003cstrong\u003eNitrogen purged\u003c\/strong\u003e The inside of the housing is purged with an inert gas (nitrogen), which eliminates condensation of moisture on the internal surfaces during temperature changes. As a result, the optics do not fog up from the inside, and there is no corrosion of materials under the influence of moisture. The air is removed from the device and replaced with an inert gas (in this case nitrogen), which does not contain water vapor and does not condense.\u003c\/li\u003e\u003cli\u003e \u003cstrong\u003eMagnesium alloy body\u003c\/strong\u003e The body is made of durable magnesium alloy to reduce weight and protect internal mechanisms.
