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.
