Lightweight yet durable, it features integrated cable management clips for a clean, professional setup favored by serious astronomers.

## 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 8" 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: Great product for SCT. - Top quality and does what it's supposed to do. Works well with the Thousand Oak dew heater controller. Easy to install.
Review: Helps see the stars instead of moisture - I have a very nice telescope. The problem is the condensation on the lens (all). I use it in central Florida at our retreat out in the country. The moisture is terrible for scopes at wee hours of the morning and I have not been able to use this wonderful scope ( all computerized) for over a year because of the parts I wanted were made in Russia by a small business i learned about on telescope Web sites, but the Russian war made it impossible to buy it until they moved part of their business to USA just for Americans. I saw this and could not wait to get it for my scope. Works like a Florida dream. Highly recommend if you watch the stars late at night for hours. Just have a good battery (deep cell) to keep your tele warm.

### ⭐⭐⭐⭐⭐ Helps see the stars instead of moisture
*by M***Y on August 15, 2024*

I have a very nice telescope. The problem is the condensation on the lens (all). I use it in central Florida at our retreat out in the country.

### ⭐⭐⭐⭐⭐ First Use-First Impression
*by N***N on November 20, 2023*

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.
