Celestron 11? Dew Heater Ring

The Celestron 11? Dew Heater ring is a great idea and a great product from Celestron! The ring replaces the original ring and installs by removing eight small screws and removing the original ring and the gasket. The dew heater ring slides into place with cut out notices indicating how to set the ring. Replace the screws following the instructions using a ?star pattern? and your ready to go! The new ring includes all data and looks great! Also has a retaining clip to ensure no damage to cables and makes cable management easier! Well done Celestron!!

An essential tool for any stargazer, the Celestron 9.25" Dew Heater Ring is designed to provide optimal dew prevention for your Celestron telescope. This indispensable accessory enhances your astronomical observing or imaging experiences throughout the year. The Dew Heater Ring is specifically designed to permanently attach to your 9.25" Celestron Schmidt-Cassegrain and EdgeHD optical tubes, replacing the existing retaining ring, ensuring it's always ready for use.

The installation process is straightforward and quick, making this Dew Heater Ring a user-friendly addition to your telescope setup. The Dew Heater Ring replaces the standard plastic retaining ring on your Schmidt corrector lens, providing efficient and direct heating across the lens surface. Crafted from lightweight yet durable aluminum, the ring's sturdy frame supports both the cable circuitry and the telescope's Schmidt corrector lens.

Unlike other heating bands or strips that indirectly heat the lens cell, the Celestron Dew Heater Ring directly warms the corrector glass. This direct approach ensures the most efficient heat transfer, effectively preventing dew formation. The ring simply plugs into an external 12V DC power source, delivering consistent, continuous heat that prevents dew formation even in heavy dew conditions.

The Dew Heater Ring is equipped with two storage clips to securely hold the power and thermistor jacks when not in use, while also accommodating the telescope's dust cover. Additionally, a cable management clip is included that attaches to the telescope's front cell, preventing the power and thermistor jack from dangling and reducing unwanted stress on the cable connection to the rings.

The Dew Heater Ring package includes the Dew Heater Ring, 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). The controller utilizes the ring's built-in thermistor and its internal environmental sensor to deliver the precise amount of heat needed to prevent dew based on the ambient temperature, humidity, and the temperature of the Schmidt corrector. This smart technology can significantly reduce the ring's power draw, thereby extending battery life. The ring also comes with an extension cable for easy connection to the controller's heater output ports or a third-party controller's heater output port.

Celestron Dew Heater Ring Features

  • Heater ring provides the most efficient heating directly to the corrector lens to prevent the formation of dew
  • Permanently mounts to your existing telescope tube for a seamless look-plus, you'll never forget to bring it with you
  • Integrated thermistor continuously monitors the temperature of the corrector lens when used with the Celestron Smart DewHeater Controllers
  • Rigid, lightweight, and durable aluminum construction
  • Included storage clip and cable management clip keep your cables organized
