Celestron Dew Heater Ring - 8"

Celestron Dew Heater Ring – 8" | Advanced Dew Prevention for Celestron Telescopes

The Ultimate Dew Prevention Solution for 8” Celestron SCT, EdgeHD & RASA Telescopes

The Celestron Dew Heater Ring is a permanent, highly efficient dew prevention system, designed to replace the plastic retaining ring on your Schmidt corrector lens. Unlike traditional dew heating bands, this ring directly heats the corrector glass, ensuring even heat distribution for maximum efficiency.

Compatible with 8" Schmidt-Cassegrain, EdgeHD, and RASA telescopes, the Dew Heater Ring minimises power consumption while delivering consistent and reliable dew prevention, making it an essential accessory for astronomers and astrophotographers.

Key Features & Benefits

Direct Heating for Maximum Efficiency

• Unlike external heating bands, the ring heats the Schmidt corrector glass directly, preventing dew formation more effectively.
• More efficient heat transfer, ensuring even warmth across the lens without overheating the surrounding components.

Lightweight, Rigid Aluminum Construction

• Replaces the telescope’s plastic retaining ring, maintaining structural integrity while supporting the internal heating elements.
• Durable yet lightweight aluminum build ensures a secure fit without adding unnecessary weight.

Compatible with 8” Celestron SCT, EdgeHD & RASA Telescopes

• Seamlessly integrates into Celestron’s 8” optical tubes, offering a custom-fit heating solution.
• Ideal for deep-sky observing and long-exposure astrophotography in humid conditions.

Plug & Play 12V DC Power Input

• Works with any standard 12V DC power source for continuous heating and all-night performance.
• Prevents dew buildup even in high-humidity environments.

Integrated Cable Management for Clean Setup

• Includes a cable management clip that secures power and thermistor jacks, preventing cables from dangling.
• Minimises accidental disconnections and protects cables from strain.

Optimised for Use with Celestron Smart DewHeater Controller (Sold Separately)

• Built-in thermistor sensor works with Celestron’s Smart DewHeater Controllers, automatically adjusting heat levels based on:
  ✔ Ambient temperature
  ✔ Humidity
  ✔ Corrector lens temperature
• Dynamically reduces power draw, extending battery life without compromising dew protection.

Compatible with Third-Party Dew Controllers

• Includes an extension cable for easy integration with third-party controllers (thermistor compatibility limited to Celestron controllers).

Pair with a Dew Shield for Maximum Efficiency

• Using a dew shield (sold separately) reduces power consumption, allowing the heater ring to operate more efficiently and prolong battery life.
