Celestron Thermistor for Smart DewHeater Controllers

Celestron Thermistor for Smart DewHeater Controllers – Precision Dew Control for Third-Party Heating Bands

Maximise efficiency and extend battery life by adding the Celestron Thermistor to your dew control setup. Designed for use with the Celestron Smart DewHeater Controller (sold separately), this sensor takes the guesswork out of using third-party heating bands or dew straps, helping you maintain clear optics without overdriving your heater and draining your power supply.

Whether you’re observing in high humidity or setting up for an all-night astrophotography session, this thermistor helps your dew control system work smarter, not harder.

Prevent Dew. Save Power. Simplify Setup.

When paired with a third-party heating band, the Celestron Thermistor lets your Smart DewHeater Controller:

• Measure the temperature of your telescope’s corrector plate

• Automatically adjust heat output to the minimum required level

• Prevent dew from forming without wasting energy

• Protect battery power during long observing sessions

This sensor ensures your dew heater runs only when needed and at just the right temperature, extending battery life and enhancing thermal efficiency—especially valuable at remote or off-grid sites.

Easy Integration with Your Smart DewHeater System

The thermistor is quick and easy to use:

1. Attach your third-party dew heater band around the corrector plate or optical tube.

2. Slide the thermistor’s sealed probe tip under the band, making direct contact with the telescope surface.

3. Plug the thermistor and heater band into their matching ports on the Smart DewHeater Controller.

With a 6-foot cable, the thermistor offers plenty of length for flexible mounting options, accommodating refractors, SCTs, and Newtonians alike.

When Do You Need the Celestron Thermistor?

You only need this thermistor if you are:

• Using third-party heating bands with your Celestron Smart DewHeater Controller

• Looking to improve power efficiency and enable temperature-controlled operation

Note: You do not need this accessory when using Celestron Dew Heater Rings, as they already contain a built-in thermistor for automated temperature regulation.

Enhance Performance with a Dew Shield

While optional, adding a dew shield to your telescope further enhances dew prevention by reducing exposure to ambient moisture. It also reduces the workload on your heating band, helping you conserve even more power during your sessions.

Key Features:

• Enables automatic temperature regulation for third-party dew heater bands

• Designed for use with the Celestron Smart DewHeater Controller

• Prevents dew while conserving battery life

• Simple installation – sealed tip slides under heating band

• Long 6’ cable for easy integration with any telescope configuration

• Not required with Celestron Dew Heater Rings

Smarter Dew Control for Serious Observers

Whether you’re imaging through the night or hosting an outreach event, keeping your optics clear of dew is essential. The Celestron Thermistor helps your Smart DewHeater Controller run at peak efficiency—even with third-party accessories—so you can focus on the stars, not the fog.
