Observe the beauty of the starry sky at night and distant objects in nature during the day with the BT-70 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 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
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-70 binoculars produce 20x magnification. These wide angle eyepieces
offer a very good overview (field of view 3.1°) at moderate
magnification. The large 15mm eye relief 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.
