DESCRIPTION:

These large binoculars, part of the EXPLORE SCIENTIFIC BT series, provide a comfortable viewing experience with a 45-degree angle, reducing eye fatigue even when tilted. They produce bright, detailed images of celestial bodies, nature, and distant objects due to their large lenses and professional coatings. Suitable for night and twilight observation, they excel in viewing star clusters, the moon, planets, and terrestrial objects like ships and airplanes during the day.

Known as double refractor telescopes, each eye has its own complete lens telescope, enhancing depth and clarity. Constructed for outdoor use, the Explore Scientific BT-120 SF Large Binoculars feature magnesium housing for durability. They're sealed against fogging and weather conditions, and the included EXPLORE SCIENTIFIC 20mm eyepieces offer exceptional quality with a wide field of view and comfortable viewing experience.

These binoculars support interchangeable eyepieces, allowing users to adjust magnification and field of view. Compatible with EXPLORE SCIENTIFIC eyepieces, they provide a magnification range of 25x to 75x. Precise brass compression rings hold the eyepieces securely, ensuring stability during observation.

For enhanced observation of astronomical objects, users can attach compatible color and nebula filters directly onto the eyepiece sleeves. The helical single focus and adjustable interpupillary distance offer comfortable observation, even when tilted. Integrated dew caps prevent fogging in humid or cold conditions, and a metal carrying handle and tripod adapter ensure secure transportation and assembly.

To maximize the viewing experience, a sturdy photo tripod with appropriate load capacity is recommended. The binoculars can easily connect to a tripod adapter, and for optimal performance, the EXPLORE SCIENTIFIC U-Mount with field tripod is suggested. This mount provides smooth movements and tracking, minimizing vibrations for clear viewing at high magnification.
