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 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 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 at any point on the upper part 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 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 finish exploring the sky, simply store it back in the eyepiece case. This way you will 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 fog\u003c\/b\u003e\u003cbr\u003eThe cable with an RCA connector must be plugged into a suitable power source. 12 V DC power is distributed evenly along the entire sleeve with only 0.2 W\/cm. That is to say, 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 controller to save energy. Tip: as an accessory, we recommend Omegon's dew shield heater control. It allows up to 2 heated sleeves to be connected simultaneously and their performance to be adjusted 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 cold glass surfaces. Well, 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 is now 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 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\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":53581618872663,"sku":"53509","price":69.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/53509_1.jpg?v=1779016729","url":"https:\/\/astrotelescopios.com\/en-eu\/products\/manguito-calefactado-de-11-cm-para-1-25","provider":"Astro Telescopios","version":"1.0","type":"link"}
