ECCO-NTC is the adapter that allows you to use a Celestron Dew Heater Ring with the ECCO2 environmental computerized controller. Dew Heater Rings differ from standard dew heater straps, as they utilize an NTC thermistor to measure the temperature of SC or aplanatic SC telescope corrector plates without the need for an external temperature probe.
ECCO-NTC is small and lightweight, allowing you to connect it to any standard Vixen-style finder shoe and it comes with 2 grub screws to attach the main body of ECCO2. ECCO-NTC does not require external power since it’s powered directly by ECCO2.
This adapter is specifically designed to work with ECCO2 and it’s not compatible with the previous/first generation ECCO controller.
