The large oversized 50mm objectives are fully multicoated to reduce reflection and maximize light transmission through the entire optical path. Utilizing the traditional porro prism configuration gives scenes a rich depth of view for an immersive observation experience and provides a comfortable feel in the hand with a lot of surface area to maintain a sure grip. The large objectives and coatings maximize the amount of light getting to the user's eyes for exceptional low-light capabilities, and its high 10x magnification provides an immersive observation experience.\u003c\/p\u003e\n\u003cp\u003eComplementing the optical performance are construction details made for the trail. The optical tubes are nitrogen-filled and O-ring sealed for fogproof performance and to make them submersible to as much as 3.3'. The binocular sports a generous 20mm eye relief and the fold-down eyecups seal against the ocular cavity to block stray peripheral light which can dim images and effect night adjusted vision.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOptical Performance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e10x magnification\u003c\/li\u003e\n\u003cli\u003e50mm objective lenses\u003c\/li\u003e\n\u003cli\u003eBAK4 Porro prism optical path\u003c\/li\u003e\n\u003cli\u003eAnti-reflection fully multicoated optics\u003c\/li\u003e\n\u003cli\u003e262.5' field of view at 1000 yards\u003c\/li\u003e\n\u003cli\u003e50° angle of view\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eUse and Handling\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eClosed bridge configuration\u003c\/li\u003e\n\u003cli\u003eLarge knurled center focus wheel\u003c\/li\u003e\n\u003cli\u003eRight-eye diopter adjustment\u003c\/li\u003e\n\u003cli\u003e20mm long eye relief, 5.0mm exit pupil\u003c\/li\u003e\n\u003cli\u003eFold-down rubber eyecups seal against ocular cavity and block stray peripheral light\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eConstruction Details\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRubberised armouring protects against impacts and provides slip-resistant grip\u003c\/li\u003e\n\u003cli\u003eNitrogen-filled, fogproof and submersible to 3.3' (1m)\u003c\/li\u003e\n\u003cli\u003eInternal focusing system helps to maintain waterproof seals\u003c\/li\u003e\n\u003cli\u003eTripod mountable with optional adapter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eSPECIFICATIONS\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePrism Type\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ePorro\u003cbr\u003e\u003cstrong\u003eMagnification\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e10x\u003cbr\u003e\u003cstrong\u003eObjective Lens Diameter\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e50 mm\u003cbr\u003e\u003cstrong\u003eAngle of View\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e5.0°\u003cbr\u003e\u003cstrong\u003eField-of-View\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e262.5' @ 1000 yd \/ 87.15 m @ 1000 m\u003cbr\u003e\u003cstrong\u003eMinimum Focus Distance\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e18.2\" \/ .46 m\u003cbr\u003e\u003cstrong\u003eExit Pupil Diameter\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e5.0 mm\u003cbr\u003e\u003cstrong\u003eEye Relief\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e20 mm\u003cbr\u003e\u003cstrong\u003eInterpupillary Adjustment\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003eNot Specified By Manufacturer\u003cbr\u003e\u003cstrong\u003eDioptric Correction\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eNot Specified By Manufacturer\u003cbr\u003e\u003cstrong\u003eFocus Type\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003eCentre\u003cbr\u003e\u003cstrong\u003eTripod Mount\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eYes (Adapter Optional)\u003cbr\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e7.2 x 7.0 x 3.1\" \/ 18.29 x 17.78 x 7.87 cm\u003cbr\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e37.4 oz \/ 1060.29 g\u003c\/p\u003e","brand":"PENTAX","offers":[{"title":"Default Title","offer_id":44014154874991,"sku":"65872","price":219.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/Pentax_SP_1050_WP_Porro__74754.jpg?v=1766573190"}],"url":"https:\/\/ontariotelescope.com\/collections\/astronomy-binoculars-pentax.oembed","provider":"Ontario Telescope and Accessories","version":"1.0","type":"link"}
