Make your astronomical and terrestrial observations more immersive with the BT-70 SF 70mm Waterproof Porro Prism Large Binoculars. Designed for the avid stargazer and nature enthusiast, these binoculars offer a stellar combination of durability, high-quality optics, and advanced features that set them apart from the competition.
Crafted with a sturdy magnesium housing, the BT-70 SF binoculars are not only lightweight but also robust enough to withstand the rigors of outdoor use. The waterproof and nitrogen-filled construction ensures that internal optics remain clear and fog-free, even in challenging weather conditions, making them a reliable choice for all your adventures.
The large 70mm objective lenses are a gateway to the cosmos, providing exceptional light-gathering capabilities that result in bright and brilliant images. Whether you're observing globular star clusters, gas nebulae, or the moon's craters, these binoculars deliver vivid and detailed views. During the day, their powerful magnification brings distant landscapes, wildlife, and even ships and airplanes into sharp focus.
Experience the comfort of prolonged viewing sessions thanks to the 45-degree viewing angle and the long eye relief (LER) eyepieces. The soft silicone eyecups can be turned inside out to suit your preference, and the generous 15mm eye relief ensures a comfortable viewing experience without eye strain.
Included with the binoculars are two high-quality EXPLORE SCIENTIFIC 20mm eyepieces from the renowned 62-degree LER series. These eyepieces offer a wide apparent field of view and a 20x magnification, providing an expansive 3.1-degree field of view. The eyepieces are also interchangeable, allowing you to customize the magnification and field of view with any 1.25 inch / 31.7mm diameter eyepieces.
For astronomers, the binoculars' flat and sharp image field is particularly impressive, enhancing your daytime observations as well. The eyepieces are argon-filled, adding to their durability and ease of maintenance.
The BT-70 SF binoculars feature a helical single focus mechanism for precise focusing and extendable dew caps to prevent fogging of the outer lenses. An integrated carrying handle ensures easy transport and secure handling during tripod assembly.
For optimal stability, a sturdy photo tripod with the appropriate load capacity is recommended. The binoculars connect via standard photo tripod threads, and for an even better experience, the EXPLORE SCIENTIFIC U-Mount with field tripod is the ideal companion for these large binoculars.
Elevate your viewing pleasure with the BT-70 SF 70mm Waterproof Porro Prism Large Binoculars, and discover the finest details of the night sky and distant horizons with unparalleled clarity and comfort.
