SvBony SV172 Dew Heater for Telescopes and Camera Lens, 240mm
Designed for astronomy telescopes and cameras, protecting optical devices like telescopes and cameras from fogging or freezing
Prevents dew condensation from forming on the glass surface
Provides even heat distribution. Power-efficient design will not result in an extra drain on your power supply.
Three-speed regulator strong-medium-weak heating modes, you can adjust the temperature in different situations
Width of the 50mm narrow width design, will not block your field of view and will not have dark corners in the field
Great heat preservation effect: Imitating OK cloth, SBR and Black-T three-layer keep warm material fits the lens better, fast and even heating
Alloy fiber heating wire provides super fast and continuous warming, silicone insulation process can prevent internal short circuit
Measure the circumference of the telescope tube or camera lens (or measure the tube diameter - not the scope aperture - ×3.14). Compatible with OD of telescopes/lenses below 76mm

SvBony SV192 Dew Heater 12V for Telescopes and Camera Lens, 560mm
Prevents dew condensation from forming on the glass surface.
Provides even heat distribution. Power-efficient design will not result in an extra drain on your power supply.
5.5X2.1 female interface design,easy connected to various 12V power inputs;
Protect optical equipment such as telescopes from fogging or freezing.
Three-speed regulator with medium-weak heating mode. Adjust temperature according to different usage requirements. Super-fast continuous heating, quick start heating;
Width of the 50mm belt will not interfere with focusing, and will not produce vignetting in the field of view;
Great heat preservation effect: imitating OK cloth, SBR, and Black-T three-layer heat preservation material, reducing heat dissipation, and no wrinkles on the inner surface after bending;
Uniform heating: the built-in aluminum film has a uniform heating surface and no dead ends;
TPE Silica power cord under low temperature won't become hard, also prevents internal short circuits.
Measure the circumference of the telescope tube or camera lens (or measure the tube diameter - not the scope aperture - ×3.14). Compatible with OD of telescopes/lenses below 178mm
