Barska Escape Porro 10-30X60 Zoom Binoculars, Black (Ab11050), Green Lens. The 10-30x60 Escape Zoom Binoculars from Barska are designed for long-distance terrestrial and astronomical viewing. The powerful variable magnification range allows the viewer to scan a large field of view and then zoom in on the selected object to make detailed observations. Even at the midrange magnifications, the large objectives and respectable exit pupil help to mitigate the appearance of the disorientating hand-shake that is common when using heavier, high-magnification binoculars. An ergonomically-placed zoom lever allows users to make fast magnification changes, while viewing through the eyepieces with a simple movement of their right finger. The large oversized objectives and multi-coated optics draw in copious amounts of light to push the low-light capabilities of the optic beyond dawn and dusk, while a large exit pupil at low magnification ensures complete coverage of the user's pupil when it gets fully dilated as light fades. Fold-down eyecups enable comfortable viewing with or without eyewear, and rubber armoring provide a slip-resistant grip. For long duration glassing sessions or when keeping the binoculars steady at high magnifications, they can be tripod mounted using an optional adapter.
