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).

Newtonian Secondary Mirror Heaters

For Newtonians, a secondary heater can be a clean, low-power way to prevent secondary dew (with compatibility for common controller systems).

• Newtonian Secondary heater – Small (1.25" stalks)
• Newtonian Secondary heater – Large (2" stalks)
