Giant binocular for observing the starry sky, nature, and landscape. 

Observe the beauty of the starry sky at night and distant objects in nature during the day. 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-around 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.  

A large binocular can also be called a double refractor telescope 
One complete lens telescope with 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 very relaxed. This comfortable way of observation increases the recognition of the finest details and effectively prevents rapid eye fatigue. 

Extremely robust binoculars with magnesium housing, sealed and filled with nitrogen  
The 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. 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-120 binoculars produce a 33x magnification. These wide-angle eyepieces offer a very good overview (field of view 1,8 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. 

Interchangeable eyepieces with 1.25 inch / 31.7mm plug-in diameter 
Adjust 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 degree and 82 degree series with focal lengths from 8 to 26mm. The magnification can be varied from 25x to 75x (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.  

Use of color and nebula filters for astronomical observations 
Increase 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)  

Comfortable 45 degree view and helical single focus 
The 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. 

Integrated carrying handle 
A metal carrying handle located at the center of gravity facilitates transport and ensures a secure hold during tripod assembly. 

Suitable tripods and tripod connection
When 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 available Explore Scientific U-Mount with field tripod. 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.
