The ring mounts permanently on the 9.25-inch optical tube, replacing the original retaining ring that holds the corrector plate. Installation is simple and quick.\u003c\/p\u003e\u003cp\u003eUnlike bands or heating strips that inefficiently heat the lens cell, the Celestron dew heater ring heats the corrector plate directly, delivering heat efficiently to prevent dew formation. Simply connect the ring to an external 12V power source for constant, continuous heat.\u003c\/p\u003e\u003cp\u003eFor the highest level of dew prevention while maximising energy efficiency, we recommend pairing the ring with a Smart DewHeater controller (sold separately): the controller uses the ring's built-in thermistor to deliver just the right amount of heat based on ambient temperature, humidity, and the corrector's temperature. Includes an extension cable and cable management clip.\u003c\/p\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable\u003e\u003cthead\u003e\u003ctr\u003e\u003cth\u003eFeature\u003c\/th\u003e\u003cth\u003eDetail\u003c\/th\u003e\u003c\/tr\u003e\u003c\/thead\u003e\u003ctbody\u003e\u003ctr\u003e\u003ctd\u003eCompatibility\u003c\/td\u003e\u003ctd\u003eSC and EDGE HD optical tubes 9.25\"\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd\u003eMaterial\u003c\/td\u003e\u003ctd\u003eAluminium\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd\u003ePower\u003c\/td\u003e\u003ctd\u003e12V DC\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd\u003eThermistor\u003c\/td\u003e\u003ctd\u003eBuilt-in, compatible only with Celestron Smart DewHeater controllers\u003c\/td\u003e\u003c\/tr\u003e\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Celestron","offers":[{"title":"Default","offer_id":58017658601803,"sku":"CSCE94052","price":109.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0886\/1981\/1147\/files\/celestron-anello-anticondensa-925-01.jpg?v=1785692275","url":"https:\/\/adriasky.it\/en\/products\/celestron-dew-heater-ring-sc-edgehd-925","provider":"Adriasky","version":"1.0","type":"link"}
