As the mirror radiates heat and cools below the ambient air temperature, moisture condenses on its surface, scattering light, reducing contrast, and ultimately ending your observation or imaging run.\u003c\/p\u003e\n\u003cp\u003eThis secondary heater is the definitive solution. It gently raises the mirror's temperature just slightly above the dew point, preventing condensation from ever forming without introducing tube currents that could degrade image quality.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eA Custom-Fit Solution for 10-inch Orion Optics UK OTAs\u003c\/h3\u003e\n\u003cp\u003eUnlike generic dew straps that can be awkward to fit or may obstruct the light path, this heater is engineered by Orion Optics UK specifically for their 10-inch AG10 and ODK10 models.
