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
