Celestron 9.25-inch Dew Heater Ring

Technical Details: Celestron Dew Heater Ring - 9.25" The Celestron Dew Heater Ring serves as the perfect dew prevention solution for your Celestron telescope, enhancing your observing or imaging experiences throughout the year.

This indispensable accessory permanently affixes to your 9.25" Celestron Schmidt-Cassegrain and EdgeHD optical tube, taking the place of your retaining ring, ensuring its constant availability. The fitting procedure is straightforward and swift, with the manual providing clear instructions.

Key Features: Efficient heating across the lens Lightweight, durable aluminium construction Storage clips for power and thermistor jacks Cable management clip Compatible with Celestron Smart DewHeater Controllers How it works The Dew Heater Ring replaces the plastic retaining ring on your Schmidt corrector lens for efficient heating across the lens.

The ring is constructed of lightweight, durable aluminium. Its rigid frame supports the cable circuitry and the telescope's Schmidt corrector lens.

Unlike other heating bands or strips that inefficiently heat the lens cell to warm the glass, the Celestron Dew Heater Ring heats the corrector glass directly, providing the most efficient transfer of heat to prevent dew formation.

Simply plug the ring into an external 12V DC power source for consistent, continuous heat that will prevent dew from forming even under heavy dew conditions. The Dew Heater Ring features two storage clips to keep the power and thermistor jacks secure when not in use while accommodating the telescope's dust cover.

The Dew Heater Ring also comes with a cable management clip that connects to the telescope's front cell. Corral the power and thermistor jack to prevent them from dangling and reduce unwanted pulls on the cable connection to the rings. Enhance your setup To achieve the highest level of dew prevention while maximising power efficiency, we strongly recommend pairing the Dew Heater Ring with a Smart DewHeater Controller (sold separately).

The controller uses the ring's built-in thermistor and its internal environmental sensor to provide just the right amount of heat to the corrector to prevent dew based upon the ambient temperature, ambient humidity, and temperature of the Schmidt corrector, which can dramatically reduce the ring's power draw, greatly increasing battery life.

The ring also includes an extension cable for connecting the ring directly to one of the controllers' heater output ports, or to a third-party controller's heater output port. (Note: the ring's integrated thermistor is only compatible with the Celestron Smart DewHeater Controllers).

Top Three Features: Celestron Dew Heater Ring - 9.25" Efficient heating across the lens: The Celestron Dew Heater Ring directly heats the corrector glass, providing the most efficient transfer of heat to prevent dew formation.

This feature ensures clear and unobstructed viewing even under heavy dew conditions. Simply plug the ring into an external 12V DC power source for consistent, continuous heat. Lightweight, durable aluminium construction: The Dew Heater Ring is constructed of lightweight, durable aluminium.

Its rigid frame supports the cable circuitry and the telescope's Schmidt corrector lens, ensuring the longevity and reliability of the accessory. This feature enhances the overall durability of your telescope setup.

Compatible with Celestron Smart DewHeater Controllers: The Dew Heater Ring is compatible with the Celestron Smart DewHeater Controllers, which use the ring's built-in thermistor and its internal environmental sensor to provide just the right amount of heat to the corrector to prevent dew based upon the ambient temperature, ambient humidity, and temperature of the Schmidt corrector.
