Globular star clusters, glowing gas nebulae, the moon with its craters and even planets can be observed wonderfully on a clear night. But also all other distant things in nature and landscape, even ships and airplanes can be seen in detail. With the all-round binoculars of the EXPLORE SCIENTIFIC BT series, you can get up very close. Thanks to the large, light-gathering lenses and the professional coatings on all lens surfaces, these binoculars produce bright and brilliant images even at night and at twilight, providing a special viewing pleasure. The comfortable 45 degree viewing angle allows fatigue-free use even when the binoculars are tilted strongly.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cb\u003eA large binocular can also be called a double refractor telescope \u003c\/b\u003e\u003cbr\u003eOne complete lens telescope with the full light gathering power is available per eye. Experience a whole new dimension of observing. Objects are reproduced almost vividly in these binoculars and observing with both eyes is basically very relaxed. Last but not least, this comfortable way of observation increases the recognition of the finest details and effectively prevents rapid eye fatigue. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cb\u003eExtremely robust binoculars with magnesium housing, sealed and filled with nitrogen  \u003c\/b\u003e\u003cbr\u003eThe BT series binoculars are designed for tough outdoor use. The IPX6 sealed and nitrogen-filled design effectively prevents fogging of the internal optics even under difficult weather conditions. The very light magnesium housing saves weight and makes it easy to handle. Two EXPLORE SCIENTIFIC 20mm eyepieces of the 62 degree LER series already included. EXPLORE SCIENTIFIC is an established manufacturer of extremely high-quality eyepieces in the astronomy scene. An optical system is only as good as its weakest component. Therefore we have decided to deliver these giant binoculars with a pair of quality eyepieces of the 62 degree LER series. With an apparent field of view of 62 degrees and a focal length of 20mm, the BT-70 binoculars produce a 20x magnification. Thus these wide angle eyepieces offer a very good overview (field of view 3.1 degree) at moderate magnification. The large interpupillary distance of these LER (long eye relief) eyepieces of 15mm and soft silicone eyecups, which can be turned inside out, also guarantee a comfortable and relaxed view. For astronomy, a flat and sharp image field is advantageous and offers a particularly impressive viewing experience even during the day. Due to the waterproof design and the argon filling, these eyepieces are absolutely durable and easy to clean. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eInterchangeable eyepieces with 1.25 inch \/ 31.7mm plug-in diameter \u003c\/b\u003e\u003cbr\u003eAdjust the magnification and field of view to your individual needs and choose from a wide range of available eyepieces. All eyepiece types with a plug-in diameter of 1.25 inch \/ 31.7mm can be used with the binoculars of the BT series. Especially recommended are EXPLORE SCIENTIFIC eyepieces of the 62 and 82 degree series with focal lengths from 8 to 26mm (see item No. 02188xx and 02196xx). The magnification can be varied from 15x to 50x (focal length binoculars : focal length eyepiece = magnification). The eyepieces are held in the binoculars by a precise brass compression ring clamp and guarantee a tilt free position.  \u003cbr\u003e\u003cbr\u003e\u003cb\u003eUse of color and nebula filters for astronomical observations \u003c\/b\u003e\u003cbr\u003eIncrease the contrast and visibility of objects and details by screwing the corresponding filters directly into the thread of the eyepiece sleeves. The use of color and nebula filters must of course always be done in pairs. Suitable are all EXPLORE SCIENTIFIC screw filters with 1.25inch \/ 31.7mm diameter (see item No. 03102xx)  \u003cbr\u003e\u003cbr\u003e\u003cb\u003eComfortable 45 degree view and helical single focus \u003c\/b\u003e\u003cbr\u003eThe 45-degree viewing angle allows a relaxed observation position even when the binoculars are tilted strongly. Also the individual interpupillary distance can be adjusted in a range from 54 to 76mm. With the fine helical individual focusing, precise focusing is achieved effortlessly. Extendable dew caps The integrated dew caps can be removed in high humidity and cold conditions. This avoids fogging of the outer objective lenses and effectively shields additional control light coming in from the side. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eIntegrated carrying handle \u003c\/b\u003e\u003cbr\u003eA metal carrying handle located at the center of gravity facilitates transport and ensures a secure hold during tripod assembly. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eSuitable tripods and tripod connection\u003cbr\u003e\u003c\/b\u003eWhen using these large binoculars, a sturdy photo tripod with an appropriate load capacity is highly recommended. The connection is made via two 1\/4 inch or one 3\/8 inch threaded holes (standard photo tripod thread) in the tripod adapter of the binoculars. The ideal solution is to use the optional availlable EXPLORE SCIENTIFIC U-Mount with field tripod (item No. 01-14300). This is specially designed for the large binoculars of the BT series and carries these devices absolutely safely. The excellent mechanism with adjustable friction in both axes allows easy moving and tracking. The binocular position is kept stable depending on the adjusted friction intensity. Vibrations are reduced to a minimum by the massive construction of the U-Mount and the large stainless steel tripod. Even at high magnification there are no vibrations and the finest details can be observed.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eCA Residents: \u003ca rel=\"noopener\" aria-label=\"Prop 65 WARNING(S) - Opens in a new tab\" href=\"https:\/\/explorescientificusa.com\/pages\/prop65\" target=\"_blank\"\u003eProp 65 WARNING(S)\u003c\/a\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eSPECIFICATIONS:\u003c\/p\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eItem Number\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e01-14200\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eOptical design\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003eAchromatic refractor Porro\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eMirror \/ lens diameter\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e70 mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eFocal length\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e400 mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eFocal ratio\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e5.7\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eApparent Facial field\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e62 degrees\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eType of remuneration\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003eEnhanced Multilayer Desposition (EMD)\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eExit pupil min.\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e3.5 mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eField of view\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e3.1 degrees\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eWaterproof\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003eYes\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eWater resistance protection level\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003eIPX6\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eExit pupil distance\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e15 mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eTotal length\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e370 mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eTotal width\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e213 mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eTotal height\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e122 mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eTotal net weight\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e3400 g\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eHousing material\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003eMagnesium\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\u003cspan class=\"speccell\"\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cp\u003eWARRANTY:\u003c\/p\u003e\n\u003cp\u003eExplore Scientific offers free collimation service for the Giant Binoculars for the lifetime of the product.
