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 night of observation is over. But it doesn't have to be this way. The Omegon dew shield heat strips keep moisture away and guarantee a super sharp view throughout the night.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eAdvantages at a glance:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe heated sleeve keeps the telescope, finder scope, and eyepieces fog-free.\u003c\/li\u003e\n\u003cli\u003eEasy adjustment: flexible strap for a perfect fit.\u003c\/li\u003e\n\u003cli\u003eVelcro closure: attaches anywhere on the upper part of the heated sleeve.\u003c\/li\u003e\n\u003cli\u003eUSB plug with a 2-meter long 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 of dew on an optical surface. When entering a warm room from the cold. Suddenly, a thin mist of water droplets settles on the glasses because warm air condenses on the cold glass surfaces. Exactly the same thing happens on 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 sleeve around the optical tube or eyepiece at the beginning of your observing session. It fits like a glove and is secured by means of a self-adhesive closure. And when you're done exploring the sky, just put it back in the eyepiece case. This way you'll always have the telescope heating at hand, for a clean optical tube.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eKeeps your optics fog-free\u003c\/b\u003e\u003cbr\u003eJust 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 sleeve 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 sleeve 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 power evenly across the entire strip at just 0.2 watts per centimeter. What this means for you: Your heated sleeve effectively keeps the temperature a few degrees above the outside temperature. Dew no longer stands a chance. In addition, its power consumption is minimal and therefore does not damage 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 sleeve with cable and USB plug\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Omegon","offers":[{"title":"Default Title","offer_id":53581619396951,"sku":"58021","price":81.82,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/58021_1.jpg?v=1779016744","url":"https:\/\/astrotelescopios.com\/en-efta\/products\/manguito-calefactado-fogfree-usb-30cm","provider":"Astro Telescopios","version":"1.0","type":"link"}
