  • PrimaLuceLab Dew Heater for 180mm Diameter Telescopes

    The PrimaLuceLab Dew Heater for 180mm Diameter Telescopes is engineered to fit optical tubes from 160mm to 200mm, protecting your optics from session-ending condensation. Operating on a standard 12V supply, this heater draws 1170mA to gently warm your telescope and keep the glass surface above the dew point, which is critical for sealed optical tubes like Schmidt-Cassegrains and refractors.

    12V, 1170mA Dew Prevention for 160-200mm Tubes

    This heater delivers consistent, gentle heat to prevent moisture from forming on your corrector plate or objective lens. It operates on a common 12V DC power source and consumes 1170mA, providing enough power to combat heavy dew without introducing tube currents. The elastic construction ensures a snug fit on any telescope with an outer diameter between 160mm and 200mm, making it a flexible solution for various mid-sized instruments.

    Secure Velcro Fit with EAGLE Compatibility

    Installation is simple and secure thanks to a robust Velcro fastener that ensures strong, uniform contact around the optical tube. This dew heater is designed to be powered and controlled directly from a PrimaLuceLab EAGLE computer, integrating seamlessly into the PLAY software ecosystem. For users without an EAGLE, it can be connected to any 12V external power source with a standard RCA connector, such as a standalone dew controller or a portable power tank.

  • How do I power the PrimaLuceLab 180mm Dew Heater?

    The dew heater requires a 12V DC power source with an RCA-style connector. It is designed for native integration with the power ports on a PrimaLuceLab EAGLE, but it works perfectly with third-party dew controllers or portable 12V batteries that have an RCA output.

    Will this PrimaLuceLab dew heater fit my 8-inch SCT?

    Yes, most likely. While an 8-inch aperture corresponds to 203mm, the physical outer diameter of the optical tube is typically smaller. This heater's compatible range of 160mm to 200mm is designed to fit many popular 6-inch refractors and 8-inch Schmidt-Cassegrain or Maksutov-Cassegrain telescopes. Always measure your telescope's tube diameter to confirm a perfect fit.

    Is the 1170mA power draw of this dew heater high for a field battery?

    The 1170mA (or 1.17A) power draw is a moderate load that must be factored into your total power budget for a night of imaging. When connected to a controller like the EAGLE, the heater will cycle on and off, reducing average consumption. If connected directly to a battery without a controller, it will draw this current continuously.

    What is the advantage of using the PrimaLuceLab 180mm Dew Heater with an EAGLE?

    When connected to an EAGLE, you can control the power output to the heater directly from the EAGLE Manager or PLAY software. This allows for precise, automated temperature management, reduces cable clutter by using the EAGLE's integrated power ports, and simplifies your entire imaging setup.

    Can I use this PrimaLuceLab dew heater without an EAGLE?

    Absolutely. You can plug it into any 12V dew controller that uses RCA output jacks. You can also power it directly from a 12V battery with an RCA port, but be aware that the heater will run at 100% power continuously, which may not be necessary and will consume battery life faster.

    Is this dew heater necessary for imaging Jupiter with a 180mm Maksutov-Cassegrain?

    Yes, it's highly recommended. Sealed optical tubes like Maksutov-Cassegrains are very susceptible to dew forming on the front corrector lens. Even a thin layer of condensation can dramatically reduce contrast and sharpness, ruining high-resolution views of planets like Jupiter and Saturn. This heater keeps the corrector clear, ensuring you capture the finest details possible.
