Optical instruments often fog up during the night. Eyepieces, lenses, and Schmidt plates: when a thin layer of dew settles on your optical instruments, your observing night is over. But it doesn't have to be that way. Omegon dew shield heat strips 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 your telescope, finder scope, and eyepieces dew-free.\u003c\/li\u003e\n\u003cli\u003eEasy adjustment: flexible strap for a perfect fit.\u003c\/li\u003e\n\u003cli\u003eVelcro fastener: attaches anywhere on the upper part 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. When entering a warm room from the cold. Suddenly, a fine mist of water droplets settles on the glasses because the warm air condenses on the cold glass surfaces. Exactly the same thing happens on 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 a self-adhesive fastener. And, when you're done exploring the sky, simply 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\u003eKeeps your optics dew-free\u003c\/b\u003e\u003cbr\u003eSimply connect the cable with the 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 cigarette lighter connection, you can use the [cms:\/\/shop\/p_id=83093 \"\"] to connect additional USB ports.\u003c\/p\u003e\n\u003cp\u003eThe direct current distributes power evenly across the entire 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 dew shield heat strips offer you more visual pleasure for longer.
