This accessory will improve your observing or imaging nights year-round. The Dew Heater Ring permanently mounts to your Celestron Schmidt-Cassegrain, EdgeHD, and RASA optical tube, replacing your retaining ring, so you'll never be caught without it. The installation process is quick and easy, as described in the manual.

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 aluminum. 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 power source.
