  • PrimaLuceLab Dew Heater for 300mm Diameter Telescopes

    The PrimaLuceLab Dew Heater for 300mm Diameter Telescopes prevents dew formation on large optics by applying gentle, consistent 12V heat. Its elastic design and Velcro fastener provide a secure fit on optical tubes ranging from 300mm to 350mm in diameter, making it ideal for large refractors and Schmidt-Cassegrains.

    Flexible Fit for 300mm to 350mm Optical Tubes

    This dew heater strip wraps securely around any optical tube from 300mm to 350mm in diameter, a common size for large amateur SCTs and refractors. The integrated elastic band and strong Velcro fastener ensure a tight, uniform connection to the tube, maximizing heat transfer and preventing condensation from forming on your objective lens or corrector plate.

    12V Power with Native EAGLE Integration

    Seamless integration with the PrimaLuceLab EAGLE is built-in, allowing you to power and control the heater directly from one of the EAGLE's power ports. The heater uses a standard 12V DC input via an RCA connector, making it universally compatible with most third-party dew heater controllers and portable 12V power supplies used in the field.

  • Will the PrimaLuceLab Dew Heater fit my 12" (305mm) SCT?

    Yes, absolutely. This dew heater is designed for optical tubes with diameters from 300mm to 350mm. A 12-inch (305mm) Schmidt-Cassegrain falls perfectly within this range, and the elastic band and Velcro will ensure a snug fit.

    How do I power the PrimaLuceLab Dew Heater if I don't have an EAGLE?

    You can power this dew heater with any standard 12V DC power source that has an RCA-style output jack. This includes most dew controller systems from other manufacturers and many portable field batteries designed for astronomy.

    Is this PrimaLuceLab Dew Heater suitable for my 14" (355mm) Dobsonian?

    While a 14" (355mm) tube is slightly outside the recommended maximum of 350mm, it may still fit, though the Velcro connection might be less secure. More importantly, this type of heater is most effective on sealed tubes like SCTs and refractors. Open-truss Dobsonians are less prone to dew on the primary mirror but may require a separate, smaller heater for the secondary mirror.

    How does the PrimaLuceLab Dew Heater attach to the telescope?

    The heater attaches using a combination of a built-in elastic band for flexibility and a strong Velcro fastener. This system allows for easy installation and removal while providing a firm, continuous contact with the optical tube for efficient heating.

    Can I leave the PrimaLuceLab Dew Heater on all night?

    Yes, it is designed for continuous operation throughout an observing or imaging session. However, like any heating element, it consumes power, which is a consideration if you are running your setup on a limited-capacity field battery. Using it with a controller that can regulate the power output is recommended for efficiency.

    What is the advantage of using the PrimaLuceLab Dew Heater with an EAGLE?

    The primary advantage is seamless integration. You can plug the heater directly into one of the EAGLE's regulated 12V power ports and control its output through the EAGLE's software interface. This centralizes your power and device management, reducing cable clutter and simplifying your astrophotography setup.
