  • Dew-Not Heater Strip - Hand Controller

    The Dew-Not Heater Strip for Hand Controllers prevents sluggish response and fogged screens in cold weather with a 4.5" strip containing a 3.5" heating element specifically sized for telescope controllers. Drawing just 2.5W of power (0.21A) at 12V DC, this heater maintains optimal operating temperatures for your electronics without significant battery drain, ensuring your GoTo system remains responsive all night.

    Thick-Film Heater for 2.5W of Even Warmth

    Unlike simple resistance-wire heaters, this Dew-Not strip uses an advanced thick-film heating element. This design distributes the 2.5W of heat more evenly across the 3.5" element surface, eliminating the hot spots and potential burnouts that can damage sensitive electronics. This efficient, uniform warmth is critical for keeping LCD screens clear and internal components responsive in freezing temperatures.

    A 4.5" Strip for Unobstructed Controller Access

    Engineered for practicality, the 4.5" strip attaches to the back of your hand controller using a simple dual rubber band system. This placement keeps the heater securely in place while leaving the entire front panel—including all buttons and the screen—completely accessible. The exterior is cloth-covered with foam insulation, directing heat into the controller for maximum efficiency.

  • Why do I need a heater for my hand controller?

    In cold weather, the liquid crystals in an LCD screen can slow down, making the display difficult to read and button presses sluggish. The Dew-Not Hand Controller Heater provides a gentle 2.5W of warmth to keep the electronics within their optimal operating temperature range, ensuring your GoTo system remains responsive and reliable.

    How does the Dew-Not Hand Controller Heater attach without blocking buttons?

    The heater is designed to wrap around the back of the controller. It uses a dual rubber band system to hold the 4.5" strip securely in place, leaving the entire front face, including all controls and the screen, completely unobstructed for normal use.

    What kind of power controller is needed for this Dew-Not heater strip?

    This heater strip requires a separate 12V DC dew controller to function. It connects via a standard RCA-style plug and is compatible with most dew control systems on the market, such as those from Dew-Not, Pegasus Astro, or ZWO. It cannot be plugged directly into a simple 12V battery without a controller.

    Observing the Orion Nebula (M42) on a cold night, my controller screen is fogging up. Will this 2.5W heater solve that?

    Yes. The 2.5W output is specifically designed to combat this exact problem. By raising the temperature of the controller body just slightly above the dew point, the Dew-Not heater will prevent condensation from forming on the screen, keeping it clear and readable while you observe targets like M42.

    What is the difference between the 4.5" strip length and the 3.5" element length on the DN016?

    The total physical length of the fabric strip is 4.5 inches. The actual heating element embedded within that strip is 3.5 inches long. This provides a non-heated margin at the ends for durability and safe handling.

    When using my Celestron NexStar+ controller in freezing temperatures, the response gets sluggish. How does the Dew-Not heater help?

    That sluggish response is a common symptom of cold electronics. The Dew-Not heater provides constant, low-level warmth to the controller's internal components. This keeps the processor and other electronics functioning at their normal speed, eliminating the input lag you experience in cold conditions with controllers like the NexStar+.
