Often, during the night, optics fog up. Eyepieces, lenses, and Schmidt plates: when a thin layer of fog forms on the optics, the observing night is over. But it doesn't have to be this way. Omegon heating strips keep dew at bay and guarantee a clear 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 strip keeps the telescope, finder scope and eyepieces free of fog.\u003c\/li\u003e\n\u003cli\u003eEasy adjustment: flexible strip for a perfect fit.\u003c\/li\u003e\n\u003cli\u003eVelcro closure: attaches anywhere on the top of the heated sleeve.\u003c\/li\u003e\n\u003cli\u003eCinch plug with 2-meter long cable.\u003c\/li\u003e\n\u003cli\u003eAvailable in different lengths.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eCompact and always at hand\u003c\/b\u003e\u003cbr\u003eSimply practical: just roll 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 finish exploring the sky, simply store it back in the eyepiece case. This way you will always have the telescope heater at hand, for a clean optical tube.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eKeep your optical tube free of fog\u003c\/b\u003e\u003cbr\u003eThe cable with RCA connector should be plugged into a suitable power source. 12V DC current distributes power evenly throughout the sleeve with only 0.2 W\/cm. This means that your sleeve maintains a temperature a few degrees above the outside temperature, thus eliminating the risk of fogging. In addition, it does not consume too much energy, so it is battery-friendly.\u003c\/p\u003e\n\u003cp\u003eThe heated sleeve can be connected with a pulse control, to save energy. Tip: as an accessory, we recommend the Omegon anti-fog heater controller. It allows you to connect up to 2 heated sleeves simultaneously and adjust their performance individually.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWhy does the optical tube fog up?\u003c\/b\u003e\u003cbr\u003eThe effects of fog on the optical tube are well known to those who wear glasses. It is generated from cold in a warm space. It suddenly leaves a layer of fog formed by fine water droplets on the glasses as warm air condenses on the cold glass surfaces. The same thing happens on the lenses of your telescope's optical tube. When the optical tube cools down, condensed water settles on the surface. But that's a thing of the past!\u003c\/p\u003e\n\u003cp\u003eWith heated sleeves you can enjoy longer and more fruitful observing sessions. While your fellow astronomers will have to pack up and go home, you can continue observing for as long as you wish.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eOther advantages:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e20 mm wide internal heating element\u003c\/li\u003e\n\u003cli\u003eSleeve width of 44 mm\u003c\/li\u003e\n\u003cli\u003eColor: black exterior and red interior\u003c\/li\u003e\n\u003cli\u003eMaterial: Cordura and nylon\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eScope of supply:\u003c\/p\u003e\n\u003cp\u003eheated sleeve with cable and RCA connector\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Omegon","offers":[{"title":"Default Title","offer_id":53581618970967,"sku":"53510","price":82.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/53510_1.jpg?v=1779016732","url":"https:\/\/astrotelescopios.com\/en-us\/products\/manguito-calefactado-de-15-cm-para-oculares-de-1-25-y-2","provider":"Astro Telescopios","version":"1.0","type":"link"}
