Heating ring for a Celestron 11 inch Schmidt-Cassegrain<\/h2>\n

The Celestron 11 inch anti-dew heating ring for SCT is the ideal dew prevention solution for your Celestron telescope<\/a>. This must-have accessory will enhance your observation or astrophotography nights all year round. The Dew Heater Ring is permanently mounted on your 11 inch Celestron Schmidt-Cassegrain optical tube and replaces the retaining ring. So that you will never run out. The installation process is quick and easy (follow the manual for instructions).<\/p>\n

How it works<\/h3>\n

The heating ring replaces the plastic retaining ring on your Schmidt corrector lens for efficient heating across the lens. The ring is made of lightweight, durable aluminum. The rigid frame supports the telescope’s cable circuit and Schmidt corrector lens. Unlike other heating bands or strips, which heat the lens cell inefficiently to heat the glass, the Celestron Dew Heater Ring heats the corrector glass directly. This allows the most efficient heat transfer to be provided to prevent dew formation.<\/p>\n

Connect<\/h3>\n

Simply plug the ring into an external 12V DC power source for consistent, continuous heat that prevents dew from forming. Even under severe (dew) conditions. The dew heater ring has 2 connectors to connect the power and thermistor. The connectors can be placed in the edge of the telescope when you are finished with the session and you want to place the dust cover on it.<\/p>\n

Also, the Dew Heater Ring comes with a cable management clip that connects to the front cell of the telescope. Guide the power and thermistor connections to prevent them from dangling and reduce unwanted pulling on the cable connection to the rings.<\/p>\n

Celestron Heating Controller<\/h3>\n

As you can see in the photo above Celestron has also released a heating controller. To achieve the highest level of dew prevention while maximizing energy efficiency. Celestron strongly recommends pairing the heating ring with a smart heating controller (sold separately). The controller uses the ring’s built-in thermistor and the internal ambient sensor to deliver just the right amount of heat to the corrector. In this way you prevent dew based on the ambient temperature, humidity and temperature of the Schmidt corrector. This reduces power consumption, significantly extending battery life. The ring also includes an extension cable to connect the ring directly to one of the heater output ports on the controllers, or to the heater output port on an external controller.<\/p>\n

Note<\/strong>: The integrated ring thermistor is only compatible with Celestron smart heating controllers.<\/p>\n

Also available from Ganymedes: Celestron’s smart dew controllers<\/h3>\n

We also have the new Celestron heating controllers available in our extensive range. We currently have 2 variants available. The cheaper variant (equipped with 2 outputs) mainly provides intelligent control of the dew ribbons and\/or rings. The more expensive version (with 4 outputs) also provides a USB hub, power supply and other smart functions for controlling your entire configuration. Important points such as cable management are also (sometimes drastically) improved.<\/p>\n
