Keep your telescope optics completely moisture-free with the Celestron 8" Dew Heater Ring. Designed specifically for 8-inch Schmidt-Cassegrain, EdgeHD, and RASA optical tubes, this high-performance telescope accessory directly warms your Schmidt corrector glass to defeat dew before it compromises your night sky viewing.
Unlike traditional heating bands that inefficiently warm the metal lens cell, the Celestron 8" Dew Heater Ring mounts seamlessly onto the optical tube by replacing the original plastic retaining ring. This direct contact provides optimal thermal conduction right where it is needed most, preventing condensation without wasting unnecessary power. Constructed from lightweight, durable aluminum, the ring supports the Schmidt corrector glass while hosting built-in storage clips and a cable management clip to prevent dangling wires. For maximum battery conservation during long astrophotography sessions, pair the ring with a compatible Celestron Smart DewHeater Controller to utilize the integrated thermistor for automated heat adjustments.
How does the Celestron 8" Dew Heater Ring attach to my telescope?
The Celestron 8" Dew Heater Ring replaces the existing plastic retaining ring on your 8-inch Schmidt-Cassegrain, EdgeHD, or RASA optical tube, securely mounting directly in contact with the Schmidt corrector lens.
What power source is required for the Celestron 8" Dew Heater Ring?
The Celestron 8" Dew Heater Ring requires an external 12V DC power source using its standard 5.5mm/2.1mm barrel connector plug, drawing up to 20 watts at maximum heat output.
Is a separate controller needed to use the Celestron 8" Dew Heater Ring?
While you can plug the Celestron 8" Dew Heater Ring directly into a standard 12V power supply, pairing it with a Celestron Smart DewHeater Controller utilizes the built-in thermistor to automatically adjust power output and dramatically conserve battery life.
