Dew Heaters & Controllers
Dew heaters are low wattage 12 Volt DC electrical heater strips that wrap around the objective lens of the telescope (as well as the finderscope and eyepieces, if desired). These warm the optics above the dew point to prevent the formation of dew. Unlike dew shields, dew heaters don't merely slow the formation of dew, they prevent its formation entirely.
