Featuring quick installation, integrated cable management, and backed by a Limited Lifetime Warranty, it’s the essential upgrade for serious astronomers committed to flawless night skies. ## Description The Celestron Dew Heater Ring is 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 is custom fit for your 11" Celestron Schmidt-Cassegrain, EdgeHD, and RASA optical tube and permanently replaces your retaining ring to provide efficient heating across the plate and so you'll never be caught without it. The process is quick and easy. The ring is constructed of lightweight, durable aluminum. Its rigid frame supports the cable circuity and the telescope's Schmidt corrector lens. Plug the ring into an external 12V DC power source for consistent, continuous heat that will prevent dew from forming. The Dew Heater Ring features two storage clips on the ring to keep the power and thermistor jacks secure while accommodating the telescope's dust cover. The Dew Heater Ring also comes with a cable management clip that connects to the telescope's front cell for a convenient location to help you corral essential cables instead of dangling and causing unnecessary weight on your corrector. Review: Sí calienta - Bastante bueno, sí calienta, aunque aún no lo pruebo en noches con mucha neblina Review: Celestron – Dew Heater Ring - I bought this Dew Heater ring for my older Celestron C9.25 XLT (non fastar compatible OTA) The product came well packaged and arrived quickly. The instructions were adequate, and if you need a little more help, there are several videos on YouTube. To be honest installation was simply. I simply pointed the OTA to Zenith (straight up), removed the screws carefully (without the included protective piece of paper), slightly flexed the original ring to help remove it, and the reverses the installation process aligning the Dew Heater Ring plugs at the 6'oclock position. This allowed me to run the power cable out between the Celestron Dew Shield cutout, and alongside/parallel to the Celestron losmandy dovetail bar and back to my SVbony power hub mounted on the top of the OTA opposite to the finderscope. I run the heater ring with another SVbony power cable with in-line adjustments (low-med-high-off) and it works perfectly in our Pacific Northwest. I've had the Dew Heater ring for a little over 6 months, and its functioned perfectly, and I like the tidy look and simplicity of the system. I will be buying another ring for my C11 EdgeHD. ## Features - DEW PREVENTION: Helps prevent dew formation on the Schmidt corrector lens for an ideal night of observing and imaging. - PERFECT FIT: Fits all 11” Celestron Schmidt-Cassegrain, EdgeHD, and RASA corrector lens with easy and quick to install - RIGID AND LIGHTWEIGHT aluminum construction that supports cable circuity. - CABLE MANAGEMENT CLIP: Additional accessory to corral essential cables and elevate unnecessary weight. - Power with an external 12V DC power source for consistent, continuous heat that will prevent dew from forming. - UNBEATABLE WARRANTY AND CUSTOMER SUPPORT: Buy with confidence from Celestron, a leading microscope and telescope brand based in California since 1960.
