Nights are not always as dry and clear as you would like. Optical surfaces will often fog up at night. And once your optics have fogged up, then your observing is over for the night. This can be avoided. Tydeux heating strips keep off the dew and help you super clear observing - all night long.

Keep your optics from fogging-up! Simply connect to a suitable power source using the lead with the USB plug supplied. The heating strip effectively maintains the temperature at an appropriate level to prevent the formation of dew. It also uses minimal energy, hence sparing your battery.

Why do your optics fog-up? A fine mist of water droplets forms on the spectacles as the warm air condenses onto the cold glass surfaces. Exactly the same happens on the lenses of your telescope optics. As your optics cool down, water condenses onto the surface. Then its time to free your view!

Highly practical! At the beginning of your observing session, simply wrap the heating strip around the OTA or your eyepiece. The strip fits like a glove and can be fixed in place using the adhesive strap fastener. After you are finished observing, just stow it back in the eyepiece case.

Tydeux strip heaters provide you with longer observing sessions. And, when other stargazers are giving up and packing up their telescopes, you can continue observing for just as long as you want!
