  • PrimaLuceLab Dew Heater for 80mm Diameter Telescopes

    The PrimaLuceLab Dew Heater for 80mm Diameter Telescopes provides active 12V heating to keep your optics free of condensation during critical imaging sessions. Drawing an efficient 670mA, it is designed with an elastic fix to fit optical tubes from 70mm to 90mm in diameter, ensuring your view remains sharp and clear all night long.

    670mA Heating for 70mm to 90mm Telescopes

    Dew formation is one of the most common frustrations in astrophotography, especially with sealed optical tubes like refractors and Schmidt-Cassegrains. This heater band gently raises the temperature of your telescope's optics just above the dew point, preventing moisture from condensing on the lens. The integrated elastic and Velcro strap ensures a secure, uniform fit on tubes ranging from 70mm to 90mm, making it a versatile solution for most 80mm-class instruments.

    12V Power via RCA and EAGLE Integration

    Engineered for seamless integration into the PrimaLuceLab ecosystem, this dew heater connects and is controlled directly from an EAGLE computer's 12V power port, eliminating the need for separate dew controllers and extra cables. For users without an EAGLE, the standard RCA connector allows it to be powered by any compatible 12V DC external power source, such as a field battery or power supply unit.

  • How much power does the PrimaLuceLab 80mm dew heater use?

    The heater is designed for efficiency, drawing 670mA from a standard 12V DC power source. This low consumption helps conserve field battery power while providing sufficient heat to prevent dew formation.

    Will the PrimaLuceLab 80mm heater fit my William Optics ZenithStar 73?

    This dew heater is designed for optical tubes with an outer diameter between 70mm and 90mm. To confirm compatibility with your ZenithStar 73 or any other telescope, measure the outer diameter of the optical tube or dew shield where you intend to place the band. If it falls within this range, the elastic and Velcro will provide a secure fit.

    Can I use this PrimaLuceLab dew heater without an EAGLE computer?

    Yes. While it is optimized for the EAGLE system, the dew heater uses a standard RCA connector and can be powered by any 12V DC source that provides sufficient amperage, such as a portable astronomy battery pack or a dedicated dew controller from another manufacturer.

    Does the PrimaLuceLab dew heater for 80mm scopes require a separate controller?

    If you are connecting it to a PrimaLuceLab EAGLE, no separate controller is needed; power output is managed through the EAGLE's software. If you are connecting it to a simple 12V battery, it will run at full power continuously. For variable control in a non-EAGLE setup, you would need to connect it to a dedicated dew controller.

    How does the PrimaLuceLab heater attach to a telescope like an Explore Scientific ED80?

    Installation is straightforward. You simply wrap the heater band around the main optical tube, just behind the front lens cell or on the dew shield itself. The integrated Velcro strap allows you to pull it snug for a secure and thermally efficient connection.

    Is the PrimaLuceLab 80mm dew heater waterproof?

    The dew heater is designed to operate in high-humidity and dewy conditions. However, it is not fully waterproof and should be protected from direct rain. Ensure all electrical connections, particularly the RCA plug, are shielded from moisture.
