EXPLORE SCIENTIFIC BT series binoculars
See 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 wonderfully observed on a clear night. But also all other distant things in nature and landscape, even ships and airplanes can be seen in detail.
Thanks to the large, bright lenses and the state-of-the-art coatings on all lens surfaces, these binoculars also produce bright and brilliant images at night and at dusk, which offer a special viewing pleasure. The comfortable 45-degree view enables fatigue-free use even when the binoculars are tilted sharply.
Large binoculars can also be called double refractor telescopes
A complete lens telescope with the full light-gathering capacity is available for each eye. Experience a whole new dimension of vision. Objects are reproduced in these binoculars almost three-dimensionally and observing with both eyes is basically very relaxed. Last but not least, this convenient way of observing 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 binoculars of the BT series are designed for tough outdoor use. The design, which is sealed according to the IPX6 standard and filled with nitrogen, effectively prevents the internal optics from fogging up, even under difficult weather conditions. The very light magnesium housing saves weight and facilitates handling.
Two 20 mm eyepieces from the 62° LER series are already included in the scope of delivery
EXPLORE SCIENTIFIC is a manufacturer of extremely high-quality eyepieces that has been established in the astronomy scene for years. With an apparent field of view of 62° and a focal length of 20 mm, these wide-angle eyepieces offer a very good overview at moderate magnification. The large eye relief of these LER eyepieces (long eye relief ) of 15 mm and soft, reversible eyecups also guarantee comfortable and relaxed viewing.
A flat field of view that is sharp right to the edge is advantageous for astronomy and also offers a particularly impressive viewing experience during the day. Due to the waterproof design and the argon filling, these eyepieces are absolutely insensitive and easy to clean.
