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 heated 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 dew.\u003c\/li\u003e\n\u003cli\u003eEasy adjustment: flexible strip for a perfect fit.\u003c\/li\u003e\n\u003cli\u003eVelcro fastener: attaches anywhere on the top of the heated sleeve.\u003c\/li\u003e\n\u003cli\u003eCinch plug with 2-meter cable length.\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 wrap the sleeve around the optical tube or eyepiece at the beginning of your observing session. It fits like a glove and is secured with a self-adhesive fastener. And, when you're done exploring the sky, just store it back in your eyepiece case. This way you'll always have your telescope heater at hand, for a clean optical tube.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eKeep the optical tube free of dew\u003c\/b\u003e\u003cbr\u003eThe cable with RCA connector must be plugged into a suitable power source. 12 V DC power distributes energy evenly along the entire 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, making it battery-friendly.\u003c\/p\u003e\n\u003cp\u003eThe heated sleeve can be connected with a pulsed controller to save energy. Tip: as an accessory, we recommend the Omegon dew 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 eyeglass wearers. It is generated from cold in a warm space. It suddenly leaves a layer of fog made of 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 keep observing for as long as you want.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eOther advantages:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eInternal heating element 20 mm wide\u003c\/li\u003e\n\u003cli\u003eSleeve width 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 delivery:\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":53581619134807,"sku":"53512","price":105.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/53512_1.jpg?v=1779016735","url":"https:\/\/astrotelescopios.com\/en-us\/products\/manguito-calefactado-de-30-cm-para-oculares-y-objetivos","provider":"Astro Telescopios","version":"1.0","type":"link"}
