With a moderate magnification and large objectives, the black Tasco 8x56 Essentials Porro Binoculars are ideal for hunting and birding, or lunar observations and comet watching. They utilize anti-reflection fully coated optics for improved light transmission, color, and clarity; with a traditional BK-7 Porro prism optical path that offers a rich depth of field. A wide exit pupil and long eye relief help to reduce the appearance of visible hand shake common to high-power optics such as these, and ensure the exiting light will completely cover the user's pupils when they are fully dilated in low light to avoid vignetting. With a comfortable feel in the hand thanks to rubberized armoring, this Essentials binocular can be mounted on a tripod with an optional adapter for hands-free use during long observation sessions.
