Often, during the night, optics fog up. Eyepieces, lenses, and Schmidt plates: when a thin layer of mist forms on the optics, the observation night is over. But this doesn't have to be the case. Omegon heated strips keep dew at bay and guarantee a clear 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 strip keeps the telescope, finder, and eyepieces free of fog.\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 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 observation session. It fits like a glove and is secured by a self-adhesive fastener. And when you finish exploring the sky, just put 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 the optical tube free of fog\u003c\/b\u003e\u003cbr\u003eThe cable with RCA connector should be plugged into a suitable power source. 12 V DC power is evenly distributed 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 to a pulse controller 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 by cold in a warm space. A layer of fog made up of fine water droplets suddenly forms 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 the heated sleeves, you can enjoy longer and more fruitful observation sessions. While your fellow astronomers have to pack up and go home, you can continue 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\u003e20 mm wide internal heating element\u003c\/li\u003e\n\u003cli\u003e44 mm sleeve width\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":53581619069271,"sku":"53511","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/53511_1.jpg?v=1779016734","url":"https:\/\/astrotelescopios.com\/en-eu\/products\/manguito-calefactado-de-20-cm-para-buscadores-de-50-mm","provider":"Astro Telescopios","version":"1.0","type":"link"}
