Ten times magnification, fixed, with a manual focus ring. If you have shopped this category you have already met the listings promising 40x60, and you already know how those end.\u003c\/p\u003e\n\n\u003cp\u003eDivide the objective by the magnification and you get the exit pupil. Fifty divided by ten is 5.0 mm, which is the width of the beam of light this optic hands your eye, and it is the entire argument for a 50 mm front lens over a pocket sized 25 mm one. That is one line of arithmetic and you can do it yourself.\u003c\/p\u003e\n\n\u003cp\u003eOn a ridge at first light, or on a boardwalk over a marsh in the last hour of the day, \u003cstrong\u003eten times magnification also means ten times your own pulse\u003c\/strong\u003e, which is why the tripod is in the box rather than sold separately.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTen times magnification through a 50 mm objective lens gives a 5.0 mm exit pupil, the widest beam of light this design can hand your eye.\u003c\/li\u003e\n  \u003cli\u003eFixed 10x magnification with a manual focus ring, so the figure on the specification is the figure you actually look through.\u003c\/li\u003e\n  \u003cli\u003eA threaded socket in the base takes the folding tabletop tripod that comes in the box, which is what holds the picture still at ten times magnification.\u003c\/li\u003e\n  \u003cli\u003eThe included clamp grips a phone between 58 and 80 mm wide against the eyepiece so you can photograph whatever you have just identified.\u003c\/li\u003e\n  \u003cli\u003eA diopter scale marked minus, zero and plus lets you set the focus once for your own eyesight and leave it set.\u003c\/li\u003e\n  \u003cli\u003eThe rubber eyecup twists down so you can use it with your glasses on instead of taking them off every time you lift it.\u003c\/li\u003e\n  \u003cli\u003eAt 6.1 inches long and 2.1 inches across it rides in a pack lid or a jacket pocket, and it arrives with a drawstring pouch, a cleaning cloth, a wrist lanyard and covers for both ends.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eTwo things it is not. The maker states no water resistance rating anywhere, so we do not claim one. And a 10x50 is a daylight and dusk instrument rather than an astronomy telescope, whatever the category likes to imply.\u003c\/p\u003e\n\n\u003cp\u003eActivearo makes gear for people who would rather be outside than reading specification sheets. This one is built so that checking the specification sheet takes you a single line.\u003c\/p\u003e\n\n\u003cp\u003eIf you want something that lives in a jacket pocket rather than a pack lid, look at our 10x25 Compact Monocular.\u003c\/p\u003e","brand":"Activearo","offers":[{"title":"Complete kit","offer_id":65696809419101,"sku":null,"price":59.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0961\/7188\/4893\/files\/1a-v3-201154-flat.png?v=1788960946","url":"https:\/\/activearo.com\/products\/high-power-monocular-10-x-50-telescope-with-tripod-and-phone-adapter","provider":"Activearo","version":"1.0","type":"link"}
