Celestron 8" Dew Heater Ring

For avid astronomers and photography enthusiasts, the Celestron 8" Dew Heater Ring is an indispensable accessory that enhances your stargazing or imaging experiences throughout the year. This innovative dew prevention solution is specifically designed for 8" Celestron Schmidt-Cassegrain, EdgeHD, and RASA optical tubes, seamlessly integrating into your setup by replacing the existing retaining ring.

This high-quality Dew Heater Ring is crafted from lightweight yet durable aluminum, providing a sturdy frame that supports both the cable circuitry and the telescope's Schmidt corrector lens. Unlike conventional heating bands or strips, the Celestron Dew Heater Ring directly heats the corrector glass, ensuring the most efficient heat transfer to prevent dew formation.

Installation is a breeze, with the Dew Heater Ring easily connecting to an external 12V DC power source. This ensures consistent, continuous heat, effectively preventing dew formation even in heavy dew conditions. The Dew Heater Ring is equipped with two storage clips, designed to secure the power and thermistor jacks when not in use, while also accommodating the telescope's dust cover.

Additionally, the Dew Heater Ring includes a handy cable management clip that attaches to the telescope's front cell. This feature helps prevent the power and thermistor jack from dangling, reducing unwanted strain on the cable connection to the rings.

The Celestron Dew Heater Ring package comes complete with the Dew Heater Ring itself, a cable management clip, a power jack extension cable, and a paper installation shield. For optimal dew prevention and power efficiency, it is recommended to pair the Dew Heater Ring with a Smart DewHeater Controller (sold separately). This controller utilizes the ring's built-in thermistor and its internal environmental sensor to provide the perfect amount of heat to the corrector, based on the ambient temperature, humidity, and the temperature of the Schmidt corrector. This smart feature can significantly reduce the ring's power draw, thereby extending battery life. The ring also includes an extension cable for easy connection to the controller's heater output port or a third-party controller's heater output port.

In conclusion, the Celestron 8" Dew Heater Ring is a stylish, functional, and durable accessory that enhances your telescope's performance by preventing dew formation, ensuring clear and unobstructed views of the cosmos.
