Product Description

The Celestron Dew Heater Ring is the ideal dew prevention solution for your Celestron 8 inch SCT telescope. This must-have accessory will improve your observing or imaging nights year-round. The Dew Heater Ring permanently mounts to your 8 inch Celestron Schmidt-Cassegrain, EdgeHD, and RASA optical tube, replacing your retaining ring, so you'll never be caught without it. The installation process is quick and easy (follow the manual for instructions).

Compatible with Dew Controllers
The Celestron Dew Ring comes with the standard RCA type lead that works with standard Dew controllers from other manufacturers, simply attach the lead from the ring to your existing dew controller for full control.

How it works
The Dew Heater Ring replaces the plastic retaining ring on your Schmidt 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 12V DC power source for consistent, continuous heat that will prevent dew from forming even under 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.

Compatability
8 inch Celestron Schmidt-Cassegrain, EdgeHD, and RASA optical tubes only. The Dew Heater Ring also comes with a cable management clip that connects to the telescope's front cell. Corral the power and thermistor jack to prevent them from dangling and reduce unwanted pulls on the cable connection to the rings.

Enhance your setup
To achieve the highest level of dew prevention while maximizing power efficiency, we strongly recommend pairing the Dew Heater Ring with a Smart DewHeater Controller (sold separately). The controller uses the ring's built-in thermistor and its internal environmental sensor to provide just the right amount of heat to the corrector to prevent dew based upon the ambient temperature, ambient humidity, and temperature of the Schmidt corrector, which can dramatically reduce the ring’s power draw, greatly increasing battery life. The ring also includes an extension cable for connecting the ring directly to one of the controllers’ heater output ports, or to a third-party controller’s heater output port. (Note: the ring’s integrated thermistor is only compatible with the Celestron Smart DewHeater Controllers).

We also recommend adding a dew shield to your setup. While not mandatory, a shield will cut down on the amount of power the Dew Heater Ring needs to keep the optics clear.

Customer Reviews

10/10  Celestron dew heater ring  A must have with a SCT if imaging for hours. Easy to fit within minutes. Ordered on Friday and delivered on Saturday. Highly recommend Harrisons for telescope gear.  (22/09/2024) Jax - Sussex


10/10  Dew Free  This is easy to fit and connect to a controller. It works by applying a gentle warmth across the whole circumference of the corrector plate through direct contact rather than through the tube assembly body as with a conventional dew heater.  (28/06/2024) Robin - Harpenden


10/10  Dew ring heater   The celestron dew ring heater is far better for my CPC 800 XLT and it works great with the aluminium dew shield far better than the strip heater because it heats the glass and not the surrounding body which is just a waste of power.  (27/08/2023) Donald MacMillan - Edinburgh
