As befits specialized astrobinoculars, this model has separate focusing on each of the eyepieces, which provides maximum image sharpness at any astronomical distance in the entire range of diopter correction. It is also worth noting that to prevent fogging, the binoculars are filled not with traditional nitrogen, but with argon, which is fully inert gases that do not react under normal conditions with other chemical elements, retaining their original properties for a long time. The eyepieces consist of five lenses grouped in three groups and provide a high level of image correction and a fairly large viewing angle. Full multi-layered illumination of all optical surfaces and BAK4 prisms transmit an image that is evenly bright throughout the entire field. The 70mm objective lens gathers enough light for double star observations, star clusters and planetary observations. Despite its primary purpose, this instrument can be successfully used for stationary landscape observations, observations of city landmarks, observations of bird migration or ship movements at sea at a distance of one kilometer or more.\u003c\/p\u003e\u003cp\u003e The aluminum body of the binoculars is highly rigid and lightweight. The classic arrangement of Porro prisms contributes to a more plastic image with a sense of three-dimensionality. The optical arrangement has allowed to reduce the minimum focusing distance to 10 meters, which is a really good indicator for binoculars of this arrangement. The accessories of the binoculars also deserve high praise. The lens caps are attached to the body with straps, which makes it impossible to lose them. The neoprene neck strap is wide enough not to squeeze the neck and shoulders when transporting the binoculars. The case, with fittings in the form of fastex, is customized for this model, thanks to which the binoculars fit perfectly in it and do not hang around inside. \u003c\/p\u003e\u003cp\u003e\u003ciframe allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\" frameborder=\"0\" height=\"475\" loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/IYv6uTbvH1I\" title=\"YouTube video player\" width=\"844\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\u003cbr\u003e\u003cul\u003e\u003cli\u003e Warranty: 12 months\u003c\/li\u003e\u003cli\u003e Brand registration country: Germany\u003c\/li\u003e\u003cli\u003e Country of origin: China\u003c\/li\u003e\u003cli\u003e Weight: 1900 g\u003c\/li\u003e\u003cli\u003e Dimensions: 290 x 215 x 85 mm\u003c\/li\u003e\u003cli\u003e Material: Aluminum with rubber coating\u003c\/li\u003e\u003cli\u003e Prism material: BAK4\u003c\/li\u003e\u003cli\u003e Additional features: Adjustment of the center distance, mm: 56 - 74 Diopter correction: -5 \/ + 5 Possibility of attaching a tripod adapter Individual focusing on each eyepiece\u003c\/li\u003e\u003cli\u003e Relative Brightness: 21.78\u003c\/li\u003e\u003cli\u003e Class: Astronomical\u003c\/li\u003e\u003cli\u003e Exit pupil diameter: 4.67 mm\u003c\/li\u003e\u003cli\u003e Twilight factor: 32.4\u003c\/li\u003e\u003cli\u003e Minimum focusing distance: 10 m\u003c\/li\u003e\u003cli\u003e Actual viewing angle: 4.4°\u003c\/li\u003e\u003cli\u003e Extended eyepiece point: 20 mm\u003c\/li\u003e\u003cli\u003e Eyeglass frames: Fold Down eyecups.\u003c\/li\u003e\u003cli\u003e Sealed construction: 100% waterproof housing\u003c\/li\u003e\u003cli\u003e Protection: Moisture-proof Gas-filled Shock-resistant\u003c\/li\u003e\u003cli\u003e Field of view at 1000 m: 77 m\u003c\/li\u003e\u003cli\u003e Zoom ratio: 15x\u003c\/li\u003e\u003cli\u003e Zoom type: Constant\u003c\/li\u003e\u003cli\u003e Construction type: Porro\u003c\/li\u003e\u003cli\u003e Type: Binoculars\u003c\/li\u003e\u003cli\u003e EAN code: 4007922058931\u003c\/li\u003e\u003cli\u003e Article number: 927553\u003c\/li\u003e\u003cli\u003e Brand: Bresser\u003c\/li\u003e\u003cli\u003e Package dimensions: 39 x 30 x 10.5 cm\u003c\/li\u003e\u003cli\u003e Package weight: 2.7 kg\u003c\/li\u003e\u003cli\u003e Color: Black\u003c\/li\u003e\u003cli\u003e Lenses: Fully Multi-Coated\u003c\/li\u003e\u003cli\u003e Maximum magnification:: 15\u003c\/li\u003e\u003c\/ul\u003e","brand":"Bresser","offers":[{"title":"Default Title","offer_id":41290371825841,"sku":"927553_sv","price":16676.58,"currency_code":"UAH","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0538\/8517\/3937\/files\/66132175380390__5e2112f29a_55437f5f-43d8-4cda-947e-c6c03fe10234.jpg?v=1754280890","url":"https:\/\/usefulrare.com\/products\/binoculars-bresser-spezial-astro-sf-15x70-wp-0114115","provider":"Dostavka","version":"1.0","type":"link"}
