Observe the beauty of the starry sky at night and distant objects in nature during the day with the BT-120 SF Giant Binoculars from Explore Scientific. Globular star clusters, glowing gas nebulae, the moon with its craters and even planets can be observed wonderfully on a clear night. 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 professional coatings on all lens surfaces, these binoculars produce bright and brilliant images, even at night and at twilight. The comfortable 45° viewing angle allows fatigue-free use even when the binoculars are tilted.
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. Two 20mm eyepieces of the 62° LER (long eye relief) series are included. With an apparent field of view of 62° and a focal length of 20mm, the BT-120 binoculars produce 33x magnification. These wide angle eyepieces offer a very good overview (field of view 1.8°) at moderate magnification. The large 15mm interpupillary distance and soft silicone eyecups, which can be turned inside out, guarantee a comfortable and relaxed view. Due to the waterproof design and the argon filling, these eyepieces are durable and easy to clean.
