Like the binoculars in the Outdoor series, this telescope packs in some nice performance at a reasonable price point. A great choice when you want to explore wildlife observation as a hobby! Thanks to the 60 mm ocular size, this scope is compact and light relative to its capabilities. Compared to larger and more expensive telescopes, the magnification factor is moderatestill, even the lowest setting is about twice that of the most common binoculars. Product dimensions and weight apply to the telescope itself, not the included tripod. The waterproof structure is useful even if you don't intend to use the scope in rain: the structure also keeps dust out, and the lenses won't fog from the inside. - BK-7 prisms - Works with or without eyeglasses - FC coating on lenses - Magnification 15 - 45 x - Field of view: 2.2 - 1.1º - Apparent field of view: 33 - 50º - Porro prism design - Tripod adapter: yes - Twilight factor: 30 - Waterproof: yes - Warranty period: 10 years - Closest focusing di
