The SVBONY SV172 320mm Dew Heater Strip is the perfect solution for preventing dew and frost from forming on larger telescope objectives, camera lenses, guide scopes, and other optical equipment during long observing sessions.
Designed for serious visual observers and astrophotographers, the SV172 gently warms your optics to stay just above the dew point, keeping images sharp and clear even in humid or cold conditions. The integrated 3-level temperature controller allows you to easily adjust the heating intensity to suit changing weather conditions while minimizing unnecessary power consumption.
Powered by any standard 5V USB power source, the heater strip is ideal for use with portable USB power banks in the field. Its premium multi-layer insulated construction ensures rapid, even heat distribution while maintaining excellent energy efficiency.
Whether you're imaging deep-sky objects or enjoying a night of visual observing, the SV172 helps ensure your session isn't interrupted by moisture on your optics.
Note: A 5V USB power source (power bank or USB adapter) is required for operation and is sold separately.
