When you enter a warm room from the cold. Suddenly, a fine mist of water droplets settles on your glasses because 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 dew shield around your optical tube or eyepiece at the beginning of your observation session. It fits like a glove and is secured by means of a self-adhesive closure. And when you're done exploring the sky, just put 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 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 dew shield comes with a USB-A plug.
