This National Geographic scope zooms 20x to 60x through a 60 millimetre objective, and the number worth understanding is the twilight factor of 34.64.\u003c\/p\u003e\n\u003ch3\u003eTwilight factor and light intensity\u003c\/h3\u003e\n\u003cp\u003eTwilight factor combines magnification and objective diameter to estimate how much detail a scope resolves in poor light. Higher is better. At 34.64 this stays genuinely useful through the first and last hour of daylight, which for game viewing and birding is most of the time you would want one.\u003c\/p\u003e\n\u003cp\u003eThe light intensity figure of 9 derives from the exit pupil and describes how much reaches your eye. Both say the same thing: the 60 millimetre objective gathers enough that high magnification will not leave you a dim image.\u003c\/p\u003e\n\u003ch3\u003eNational Geographic 20-60x60 magnification and field of view\u003c\/h3\u003e\n\u003cp\u003eAt 20x the field of view is 29 metres at 1000 metres, or 1.66 degrees, wide enough to find something and follow it. Winding to 60x narrows that in exchange for detail, which is how a zoom scope is meant to be used: locate wide, then close in. Near focus is 12 metres, so it works on something nearby as well as at distance.\u003c\/p\u003e\n\u003ch3\u003eBuild and what is included\u003c\/h3\u003e\n\u003cp\u003eThe body is metal with rubber and metal armouring, weighing 998 grams at 350 by 155 by 95 millimetres. Optics are fully coated, and removable dust caps protect both ends. A table tripod is supplied, which at 60x is not optional: hand holding at that magnification gives an unusable image however good the glass.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCompact and lightweight spotting scope for travelling and hiking\u003c\/li\u003e\n\u003cli\u003eLarge objective lens diameter for a high light gathering capacity\u003c\/li\u003e\n\u003cli\u003eTable tripod included for added stability\u003c\/li\u003e\n\u003cli\u003eMagnification range: 20x-60x\u003c\/li\u003e\n\u003cli\u003eObjective lens diameter: 60mm\u003c\/li\u003e\n\u003cli\u003eField of view: 29m@1000m (20x)\u003c\/li\u003e\n\u003cli\u003eDimensions: 350x155x95mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMagnification Zoom min.: 20\u003c\/li\u003e\n\u003cli\u003eMagnification Zoom max.: 60\u003c\/li\u003e\n\u003cli\u003eType of coating: Fully coated\u003c\/li\u003e\n\u003cli\u003eColour of coating: blue\u003c\/li\u003e\n\u003cli\u003eField of view at 1000m: 29 m\u003c\/li\u003e\n\u003cli\u003eField of view: 1.66 degrees\u003c\/li\u003e\n\u003cli\u003eLight intensity: 9\u003c\/li\u003e\n\u003cli\u003eTwilight factor: 34.64\u003c\/li\u003e\n\u003cli\u003eNear focus from: 12 m\u003c\/li\u003e\n\u003cli\u003eBody material: Metal\u003c\/li\u003e\n\u003cli\u003eBody armouring: Rubber\/Metal\u003c\/li\u003e\n\u003cli\u003eDust protection caps: for objective and eyepiece, individually removable\u003c\/li\u003e\n\u003cli\u003eNet weight (without access.): 998 g\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e1 x NATIONAL GEOGRAPHIC 20-60X60 SPOTTING SCOPE\u003c\/li\u003e\u003c\/ul\u003e","brand":"NATIONAL GEOGRAPHIC","offers":[{"title":"Default Title","offer_id":50239247646960,"sku":"15912","price":1520.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/2651\/0008\/files\/NATIONAL-GEOGRAPHIC-20-60x60-Spotting-Scope.jpg?v=1787236109","url":"https:\/\/neonsales.co.za\/products\/national-geographic-20-60x60-spotting-scope","provider":"NeonSales","version":"1.0","type":"link"}
