With two huge 100mm objective lenses, the new GiantView BT-100 delivers an immersive observing experience unlike any other. Stargazing with both eyes brings an amazing amount of depth to each view while also making each observation more relaxing and comfortable. Views of everything from lunar craters to wispy nebulae will take on an almost 3-dimensional feel in the GiantView BT-100 Binocular Telescope. This impressive instrument’s 100mm (3.9″) aperture objective lenses gather over 56% more light than large 80mm astronomy binoculars, so you’ll be able to see more objects in the sky with greater clarity. But the fun doesn’t stop at sunrise! During the day, this big binocular telescope becomes the ultimate “spotting scope” for terrestrial exploration. Set the BT-100 up on your deck or at your favorite scenic overlook to enjoy awesome long-distance views. The 45-degree angle eyepiece holders make both daytime and nighttime observations comfortable. The GiantView BT-100 Binocular Telescope includes a pair of 18mm 65-degree flat-field 1.25″ eyepieces which provide 31x magnification and a 2.13-degree field-of-view right out of the box. Individual eyepiece focusers provide precise focus control, while compression rings hold inserted eyepieces securely in-place. One of our favorite features of the BT-100 is its ability to accept pairs of interchangeable 1.25″ eyepieces so you can control magnification depending on yourobserving goals (requires two 1.25″ eyepieces of the same focal length and optical design, sold separately). For example, a pair of 10mm eyepieces will deliver a 55-power view through the 550mm focal length BT-100 (550/10 = 55). For the best results, we recommend using pairs of 6mm or longer focal length 1.25″ eyepieces with the GiantView BT-100 for the best results. The big GiantView BT-100 Binocular Telescope weighs in at 14.5 lbs. and requires a sturdy binocular mount for stable support.
