The Celestron Dew Heater Ring 9.25" for Telescopesis the ideal dew prevention solution for your Celestron telescope. This must-have accessory will improve your observing or imaging nights year-round. The Dew Heater Ring permanently mounts on your 9.25" Celestron Schmidt-Cassegrain (manufactured in 2006 or later), EdgeHD, and RASA optical tube, replacing your retaining ring so you'll never be caught without it. The installation process is quick and easy.

The Dew Heater Ring replaces the retaining ring on your corrector lens for efficient heating across the lens. The ring is constructed of lightweight, durable aluminum. Its rigid frame supports the cable circuity 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 12 VDC power source for consistent, continuous heat that will prevent dew from forming under even 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.
