Often, optical instruments fog up during the night. Eyepieces, lenses, and Schmidt plates: when a thin layer of mist settles on your optical instruments, the observation night is over. But it doesn't have to be this way. Omegon heat strips for dew shields keep moisture away and guarantee you a super sharp view all night long.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eAdvantages at a glance:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe heated cuff keeps the telescope, finderscope, and eyepieces fog-free.\u003c\/li\u003e\n\u003cli\u003eEasy adjustment: flexible strap for a perfect fit.\u003c\/li\u003e\n\u003cli\u003eVelcro fastener: attaches anywhere on the upper part of the heated cuff.\u003c\/li\u003e\n\u003cli\u003eUSB plug with 2-meter cable.\u003c\/li\u003e\n\u003cli\u003eAvailable for different tube sizes.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eWhy do your optics fog up?\u003c\/b\u003e\u003cbr\u003eAnyone who wears glasses knows perfectly well the effects that dew has on an optical surface. When entering a warm room from the cold, suddenly a fine mist of water droplets settles on the glasses because warm air condenses on the cold glass surfaces. Exactly the same thing happens to the lenses of your telescopic optics. When your optics cool down, condensed water deposits on the surface. It's time to see clearly!\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eCompact and always at hand\u003c\/b\u003e\u003cbr\u003eSimply practical: just wrap the cuff around the optical tube or eyepiece at the beginning of your observation session. It fits like a glove and is secured by means of a self-adhesive fastener. And when you finish exploring the sky, simply store it back in the eyepiece case. This way, you'll always have the telescope heater at hand, for a clean optical tube.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eKeeps your optics fog-free\u003c\/b\u003e\u003cbr\u003eSimply connect the cable with a USB plug to a suitable power source:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUp to 40 cm in length, the heated cuff comes with a USB-A plug. A small power bank or a standard USB power source that supports fast charging is sufficient. (Do not connect the USB-A plug to a computer, as in some cases its USB port could be overloaded).\u003c\/li\u003e\n\u003cli\u003eFrom 50 cm in length, the heated cuff has a USB-C plug. It requires 12 volts, which is what most USB power sources with Power Delivery (USB-PD) supply.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eTip: If your power bank has a cigarette lighter connection, you can use the [cms:\/\/shop\/p_id=83093 \"\"] to connect additional USB ports.\u003c\/p\u003e\n\u003cp\u003eThe direct current distributes energy evenly across the entire band at only 0.2 watts per centimeter. What this means for you: Your heated cuff effectively maintains the temperature a few degrees above the outside temperature. Dew no longer has a chance. In addition, its power consumption is minimal and therefore does not harm your batteries.\u003c\/p\u003e\n\u003cp\u003eOmegon dew shield heat strips offer you more viewing pleasure for longer. When other stargazers have already packed up their telescopes, you can observe for as long as you wish.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eOther highlights:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e20 mm wide heating element inside\u003c\/li\u003e\n\u003cli\u003eStrap width: 44 mm\u003c\/li\u003e\n\u003cli\u003eColor: black exterior\/red interior\u003c\/li\u003e\n\u003cli\u003eMaterial: Cordura\/nylon\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eScope of delivery:\u003c\/p\u003e\n\u003cp\u003eHeated cuff with cable and USB plug\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Omegon","offers":[{"title":"Default Title","offer_id":53581619298647,"sku":"58018","price":82.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/58018_1.jpg?v=1779016741","url":"https:\/\/astrotelescopios.com\/en-us\/products\/manguito-calefactado-fogfree-usb-11cm","provider":"Astro Telescopios","version":"1.0","type":"link"}
