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. 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.
A large binocular can also be called a double refractor telescope
One complete lens telescope with the full light gathering power is available per eye. Experience a whole new dimension of observing.
Extremely robust binoculars with magnesium housing, sealed and filled with nitrogen
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.
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 and 82 degree series with focal lengths from 8 to 26mm (see item No. 02188xx and 02196xx). 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.
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 (item No. 01-14300).
