SVBONY Lens Heater Warmer Dew Heater Strip for Telescopes and Camera Lens
What causes dew on a telescope?
-When the surface of your telescope objective or camera lens falls below the ambient temperature of the air outside, moisture begins to condense. On a night with the high humidity in the air, dew forms even more aggressively. A telescope that has been ?dewed-up? no longer captures clear images of your deep-sky objective, and instead captures a washed-out drab image resembling a flat frame.
To be a little more technical, the heat from the warmer telescope transfers to the colder outside temperature via radiation. When the telescope radiates its heat to the sky, it quickly cools down and falls below the dew point temperature. This chain of events causes condensation to form on your telescope or camera lens.
-Dew ruining your imaging process
Using dew heaters with your astrophotography rig can be the difference between shooting hours worth of exposure time on a target, and coming up empty-handed.
Dew prevention is an essential precaution needed for long exposure imaging sessions and is something you will inevitably need to address at one point or another.
-Designed for astronomy telescopes, and compatible with DSLR camera lens, spotting scope.
-Convenient USB port design
Convenient USB port design; connect it to power source with USB port, such as 5Vpower bank, car charger, laptop, desktop computer, etc.
-3 gear regulator with strong-medium-weak heating modes.
0.3 meter 3 gear regulator with strong-medium-weak heating modes. You can adjust the temperature for different use requirements. Super-fast and continuous warming with quick start up to heat.
-50mm narrow width does not interfere with focusing
50mm narrow width does not interfere with focusing, and will not produce dark corners in the field; it is also the width that reduces interference for other accessories on the lens barrel.
-Good keeping warm effect
Imitation OK cloth, SBR and Black-T three-layer keeping warm material reduces heat dissipation, and the inner surface does not fold after being bent. It fits the lens barrel better and which increases the keeping warm effect.
-Nylon charging cable, low temperature resistance
Even heating; Safe use and prevent short circuit
Even heating: the built-in aluminum film conduct even heating surface, no dead angle left.
Safe use and prevent short circuit. Alloy fiber heating wire provides super-fast and continuous heating. Silicone insulation process prevents internal short circuit.
