Starfield Dew Heater Strip
Starfield Dew Heater Strip Dew Heaters for Telescopes & Astrophotography Dew can end an imaging session fast—especially as temperatures drop toward the dew point. Starfield DH Series dew heaters are built to help keep your optics clear through long nights, with rugged straps, cold-weather-ready silicone cables, and practical sizing for common telescope and accessory diameters. Based in Toronto, Ontario, Starfield Optics supports astronomers with dew control solutions for refractors, Newtonians, guide scopes, and eyepieces. Choose the Right Dew Heater Size Strap sizes are listed by typical telescope/accessory class, but the best way to choose is to measure the circumference where the strap will mount (near the optics).
