  • Dew-Not Heater Strip - 14" Scope

    Designed specifically for 14" optical tubes, the Dew-Not DN014 Heater Strip delivers 23.0 W of consistent, evenly distributed heat from its 48" active heating element. Operating at a standard 12V DC and drawing 1.92 A, the full 49.0" (124.5cm) strip wraps securely around large OTAs to prevent dew formation on your primary mirror or corrector plate, ensuring your optics remain clear all night.

    Thick-Film Heating: 66% Active Surface Area for Even Dew Control

    Instead of using simple resistance wires, this Dew-Not strip employs an advanced thick-film heater technology. With 66% of its surface area actively emitting heat, it provides exceptionally uniform thermal distribution across your optics, eliminating the risk of localized hot spots that can affect image stability or damage coatings.

    Built for 14" OTAs: A 49" Strip with Insulated Design

    The 49.0" length is precisely sized to encircle the large barrels of 14" Schmidt-Cassegrains, Ritchey-Chrétiens, and other large optical tubes. A durable cloth cover, external foam insulation, and a secure Velcro closure ensure all 23.0 W of power are directed into your telescope, not wasted into the night air. The integrated 6' power cord terminates in a standard RCA jack for compatibility with most dew heater controllers.

    Thick-Film Advantage: Why 66% Surface Heating Beats Resistance Wire

    The core difference between Dew-Not and conventional dew heaters lies in the heating element itself. Resistance wires concentrate heat along a thin line, creating an uneven temperature gradient and risking burnouts over time. The patented thick-film design generates warmth over a broad surface, ensuring a gentle, consistent temperature just above the dew point for superior reliability and efficiency.

  • What power supply is needed for the Dew-Not 14" Heater Strip?

    The Dew-Not DN014 requires a 12V DC power source capable of supplying at least 1.92 A of current. It is designed to be used with standard astronomy dew heater controllers, which allow you to regulate the 23.0 W output based on ambient temperature and humidity.

    Will this Dew-Not heater fit my Celestron 14" EdgeHD or Meade 14" LX200?

    Yes. The 49.0" strip length is specifically designed to fit the circumference of large 14" OTAs, including popular models like the Celestron C14, EdgeHD 1400, and Meade 14" ACF/SCT series. The Velcro closure provides a secure, adjustable fit.

    How does the Dew-Not DN014 heater prevent hot spots on my telescope?

    The heater uses a patented thick-film heating element where 66% of the surface area radiates heat. Unlike traditional resistance wires that concentrate heat in thin lines, this design distributes warmth evenly across the entire 48" heating element, preventing any single point from becoming too hot and ensuring uniform dew prevention.

    Can I leave the Dew-Not Heater Strip on my 14" SCT all night during a humid imaging session?

    Absolutely. The Dew-Not heater is built for continuous, all-night operation. For best results and power efficiency, you should connect it to a dew controller that uses temperature and humidity sensors to apply just enough power to stay above the dew point, rather than running it at full power continuously.

    What is the difference between the 49" strip length and the 48" element length?

    The total physical length of the fabric and foam strip is 49.0" (124.5cm), which includes the Velcro closure. The actual heat-emitting element inside the strip is 48" long. This design ensures the entire heated portion of the strip is in contact with your telescope's optical tube.

    Is the Dew-Not DN014 heater made in the USA?

    Yes, all Dew-Not dew remover products are proudly manufactured in the USA.
