Celestron – Dew Heater Ring – Aluminum Dew Prevention – Compatible 8” Schmidt-Cassegrain, EdgeHD, RASA Telescope

The Celestron Dew Heating Ring is an absolute must-have for anyone who uses their telescope regularly, especially in humid or cool environments. After dealing with dew forming on my corrector plate during several observing sessions, this heating ring has been a game-changer. Installation was straightforward, and it integrates seamlessly with my. The heating is gentle and evenly distributed across the corrector plate, keeping it dry and clear throughout the night. I especially love that it doesn’t require constant monitoring—it just works. Pairing it with a Celestron power controller gives you more flexibility in adjusting the heat levels based on the conditions of the night. Since using this, I’ve had far fewer interruptions in my sessions, which has greatly enhanced my stargazing experience. Highly recommended for all astronomers who want to make the most out of every night, regardless of dew conditions!

Great product easy to install, but please follow the instructions

Lo usé en una sesión de observación, cuando se empezó a empañar lo puse a funcionar y en unos minutos el vidrio se limpió, así que funcióna y protege del rocío, estoy conforme con la compra, muchas gracias

I actually read the instructions before the package arrived, even though it seemed unmanly to do that. Installation was a snap. I bought it to replace the DIY heater made with Nichrome wire from a toaster and a cheap PCM controller from Amazon. It worked, but it lacked class. The Celestron heater works and has class. Dew is a nearly constant problem between the coastal marine layer and the radiation fogs from the Valley. I have heaters on all my scopes and "on" is the default position. Only one night's use so far, but it does look as if the Celestron heater ring is up to the job. The inline controller is smaller than the variable controller I was using, which makes cable routing much easier and neater.

Keeps my telescope free from dew
