Celestron DewHeater and Power Controller 4x – reliable protection against dew on optics

The Celestron DewHeater and Power Controller 4x is a special telescope accessory that protects the optics from dew (condensation). It supplies power to up to four heater bands (Dew Heaters) and allows individual control of the heating output.

• 4 independently adjustable outputs for heater bands on eyepiece, finder, or objective
• Rugged aluminum housing for durable outdoor use
• Easy integration into existing 12V power systems of telescope mounts
• Compact design saves space on the mount

What sets the Celestron DewHeater Power Controller apart

Unlike simple heater bands without regulation, the controller offers precise adjustment of the heating output per output. This keeps the optics ice-free without wasting energy. The 4 outputs allow connecting multiple heater bands, e.g., for eyepiece and finder simultaneously.

Ideal for...

This controller is aimed at astrophotographers and visual observers using telescopes. Especially on humid nights or during sudden temperature drops, dew protection is indispensable. It is also a useful addition for observatories and mobile observatories.

How to use the Celestron DewHeater Power Controller

Connect the controller to your 12V power source (e.g., Power Tank or mount socket). Insert up to four Dew Heater bands into the outputs. Position the heater bands on the eyepiece, finder, or objective. Adjust the heating power according to weather conditions using the controls.
