The Carbon Dew Heater for your 18\" ODK provides continuous, low-level heat that keeps your primary mirror's surface temperature just above the dew point. This prevents the gradual softening of focus and loss of contrast that occurs as micro-dew droplets form, ensuring your final sub-exposures are as sharp as your first.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eMy observatory is in a high-humidity location.
