  • PrimaLuceLab Dew Heater for 150mm Diameter Telescopes

    The PrimaLuceLab Dew Heater for 150mm diameter telescopes provides consistent, gentle heat to prevent session-ending condensation on your optics. Designed to fit tubes from 140mm to 160mm in diameter, it draws 1000mA from a 12V power source, making it an essential tool for observers using refractors or Schmidt-Cassegrains on humid nights.

    12V, 1000mA Heating for Dew-Free Optics

    As your telescope cools below the ambient dew point, moisture condenses directly onto your objective lens or corrector plate, obscuring the view. This dew heater counteracts the effect by applying just enough warmth to keep the optical surface clear, drawing 1000mA from a standard 12V DC source to ensure your imaging or observing session continues uninterrupted.

    Flexible Fit for 140mm to 160mm Telescopes

    Engineered for telescopes with a nominal 150mm aperture, this heater features an elastic construction that accommodates optical tube diameters from 140mm to 160mm. A secure Velcro fastener ensures the band maintains uniform contact around the tube, delivering efficient and even heat transfer right where it's needed—at the front of the optical assembly.

    Native EAGLE Control and Universal 12V RCA Power

    This dew heater is designed for seamless integration with the PrimaLuceLab EAGLE, allowing for direct power and control from the EAGLE's built-in ports. For users outside the EAGLE ecosystem, the heater includes a standard RCA connector, making it compatible with a wide range of third-party 12V dew controllers and power supplies.

  • How do I install the PrimaLuceLab Dew Heater on my telescope?

    Wrap the dew heater band around the optical tube as close to the front objective lens or corrector plate as possible. The elastic material allows it to stretch for a snug fit, and you secure it in place using the integrated Velcro fastener for strong, uniform contact.

    Will this PrimaLuceLab Dew Heater fit my 6-inch Newtonian telescope?

    Yes, most likely. A 6-inch telescope has an optical tube diameter of approximately 152mm, which falls squarely within this heater's supported 140mm to 160mm range. It is an excellent fit for preventing dew on a secondary mirror or a corrector plate on a Schmidt-Newtonian.

    Can I use the PrimaLuceLab Dew Heater without an EAGLE computer?

    Absolutely. While designed for the EAGLE system, the dew heater uses a standard 12V RCA power connector. This allows it to be plugged into any compatible external dew controller or 12V power tank that provides an RCA-style output port.

    Is this dew heater necessary for my 150mm SCT on a humid night?

    Yes, it is highly recommended. Schmidt-Cassegrain telescopes (SCTs) have a large, exposed corrector plate at the front of the tube which is extremely susceptible to dew. A dew heater like this one is often considered essential equipment for preventing condensation from forming on the corrector and ending an observing session prematurely.

    How much power does the PrimaLuceLab 150mm Dew Heater draw?

    The dew heater has a power consumption of 1000mA (1.0 Amp) when connected to a 12V power source. This is a critical figure for calculating the total power budget for your portable field setup.

    Where on the telescope tube should I place the PrimaLuceLab Dew Heater?

    For maximum effectiveness, the dew heater should be placed on the main optical tube, wrapped around the cell that holds the primary lens or corrector plate. Positioning it as far forward as possible ensures the heat is applied directly to the glass element most exposed to the night air.
