Optical instruments often fog up during the night. Eyepieces, lenses, and Schmidt plates: when a thin layer of fog settles on your optical instruments, the observing night is over. But this doesn't have to be the case. Omegon heat strips for dew shields keep moisture away and guarantee you a super-sharp 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 sleeve keeps the telescope, finder, and eyepieces fog-free.\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\u003eUSB plug with a 2-meter cable length.\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. Entering a warm room from the cold. Suddenly, a thin mist of water droplets settles on the glasses because the warm air condenses on the cold glass surfaces. Exactly the same thing happens to the lenses of your telescopic optics. When your optics cool down, condensed water settles 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, simply 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\u003eSimply 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 supplies with Power Delivery (USB-PD) provide.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eTip: If your power bank has a lighter connection, you can use the [cms:\/\/shop\/p_id=83093 \"\"] to connect additional USB ports.\u003c\/p\u003e\n\u003cp\u003eDirect current distributes power evenly throughout the band at only 0.2 watts per centimeter. What this means for you: Your heated sleeve effectively maintains 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 harm your batteries.\u003c\/p\u003e\n\u003cp\u003eOmegon heat strips for dew shields offer you more viewing pleasure for longer.
