Perfect buy
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!

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
