Description

Take the guesswork out of using third-party heating bands or straps and increase your power efficiency with the Celestron Thermistor for Smart DewHeater Controllers. This accessory allows the Smart DewHeater Controller (sold separately) to deliver just the right amount warmth for to your telescope’s corrector to prevent dew without wasting battery. 6’ cable length accommodates a wide variety of configurations.

 

How it works

Connect the heating band to your telescope and place the Thermistor's sealed probe tip under the heating band. Plug each cable into its corresponding port of the Smart DewHeater Controller

NOTE: This thermistor is not required if you are using a Celestron Dew Heater Ring because the ring already contains a built-in thermistor.

 

Enhance your setup

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

FAQ

Q:

I am using an AC Adapter which supplies 12V DC to the Smart DewHeater Controller, but the controller is not powering on. What is the problem?

A:

The AC Adapter’s power output plug must have a barrel length of at least 12mm, or it will not make a good connection with the controller’s power input jack. The Celestron AC Adapters have plug barrel lengths of 14mm, as do the power cables supplied with the Smart DewHeater Controllers.
