  • PrimaLuceLab Dew Heater for 350mm Diameter Telescopes

    The PrimaLuceLab Dew Heater for 350mm Diameter Telescopes applies 1800mA of consistent 12V power to prevent condensation on large optics. Designed with an elastic fix for tubes from 350mm to 360mm in diameter, it ensures your Schmidt-Cassegrain or refractor remains clear even on the dampest nights.

    Active Dew Prevention for 350mm to 360mm Telescopes

    Dew formation on a large corrector plate or objective lens can end an imaging or observing session prematurely. This dew heater provides active, gentle heat directly to your optical tube, raising the surface temperature just enough to prevent condensation from forming without introducing tube currents.

    Installation is straightforward thanks to a strong Velcro closure that ensures a secure, uniform fit. An integrated elastic section allows the heater to conform perfectly to optical tubes ranging from 350mm to 360mm in diameter, maintaining constant contact for efficient heat transfer.

    12V Power with Full EAGLE Integration

    Engineered for the PrimaLuceLab ecosystem, this dew heater connects directly to one of the EAGLE's power ports, allowing for software control of its heat output. This integration centralizes your power and control, eliminating extra cables and separate controllers from your setup.

    For those not using an EAGLE, the heater features a standard RCA connector, making it compatible with most third-party 12V dew controllers or a direct connection to a 12V power source. With a power draw of 1800mA, it provides ample heating power for large optics in challenging conditions.

  • How do I install the PrimaLuceLab Dew Heater on my 14-inch (355mm) SCT?

    Installation is simple. Wrap the PrimaLuceLab 350mm Dew Heater around the main optical tube, just behind the front corrector plate cell. The elastic band will ensure a snug fit on your 14-inch (355mm) tube. Secure it firmly using the integrated Velcro strip to ensure good contact with the tube for optimal heat transfer.

    Can I power the PrimaLuceLab 350mm Dew Heater from my field battery while imaging the Andromeda Galaxy (M31)?

    Yes. The PrimaLuceLab 350mm Dew Heater is designed to run on a standard 12V DC power source, which is typical for field batteries used in astronomy. It connects via a common RCA plug. Drawing 1800mA, it's an efficient solution for all-night imaging sessions of large targets like the Andromeda Galaxy (M31).

    Do I need a PrimaLuceLab EAGLE to use this 350mm dew heater?

    No. While the PrimaLuceLab 350mm Dew Heater is designed for seamless integration with the EAGLE's power and control software, it is not required. The heater uses a standard RCA-type 12V power connector, making it compatible with virtually any dew controller or 12V power tank on the market.

    What makes the PrimaLuceLab 350mm Dew Heater better than a passive dew shield?

    A dew shield can delay the formation of dew, but in high-humidity conditions, it will eventually cool to the dew point. The PrimaLuceLab 350mm Dew Heater provides active heating to keep the optics' temperature consistently above the dew point, offering a guaranteed solution that works all night, regardless of humidity levels.

    Will this PrimaLuceLab 350mm dew heater get too hot and affect my telescope's image quality?

    No. The heater is designed to provide low, gentle warmth. When used with a controller (like the EAGLE or a third-party unit), you can regulate the power to apply just enough heat to prevent dew, without introducing heat waves or tube currents that could degrade image sharpness.

    How does the Velcro on the PrimaLuceLab 350mm Dew Heater hold up in cold weather?

    The materials used in the PrimaLuceLab 350mm Dew Heater, including the Velcro fastener, are selected for reliable outdoor use in typical nighttime observing temperatures. The Velcro provides a strong, secure closure that will not fail or become brittle in the cold.
