PrimaLuceLab Dew Heater for 200mm Diameter Telescopes
The PrimaLuceLab Dew Heater for 200mm Diameter Telescopes delivers consistent, low-power 12V heating to prevent dew from forming on your primary optics. Designed specifically for optical tubes around 200mm, it's an essential tool for maintaining clear views through refractors and Schmidt-Cassegrains on humid nights.
12V Active Heating for 200mm Schmidt-Cassegrains and Refractors
Dew formation on a corrector plate or objective lens can end an imaging or observing session prematurely. Gentle, continuous 12V warmth is applied directly to the optical tube, keeping the glass surface just above the dew point without introducing tube currents. This heater is particularly effective on sealed optical tubes like SCTs and refractors, which are prone to rapid dewing during long exposures or in damp conditions.
EAGLE Integration and Universal 12V RCA Power
This heater is designed for seamless integration with the PrimaLuceLab EAGLE, connecting directly to one of its 12V power ports for software-based control. For users without an EAGLE, the standard RCA connector allows it to be powered by any common 12V dew controller or portable battery pack. The secure Velcro and elastic fastening system ensures a snug fit on 200mm optical tubes, delivering uniform heat transfer across the band.

How do I power the PrimaLuceLab Dew Heater for my 200mm telescope?
You can power it directly from a PrimaLuceLab EAGLE computer's 12V output. Alternatively, it uses a standard RCA-style plug, making it compatible with most third-party dew heater controllers and 12V DC power supplies.
Will this PrimaLuceLab dew heater fit my 8" (203mm) SCT?
No. This heater is specified for tubes from 180mm to 200mm in diameter. An 8" (203mm) Schmidt-Cassegrain has a tube wider than 200mm, so it needs a larger PrimaLuceLab dew heater.
Can I leave the PrimaLuceLab Dew Heater on all night?
Yes, it's designed for continuous operation. For best results and power efficiency, it should be connected to a controller (like the EAGLE or a dedicated dew controller) that can regulate the power output based on ambient temperature and humidity.
What's the advantage of using this heater with a PrimaLuceLab EAGLE?
When connected to an EAGLE, you can control the heater's power output through the EAGLE's software. This allows for automated, temperature-based dew prevention, optimizing power consumption and preventing overheating, all managed from a single control interface.
How do I install the PrimaLuceLab 200mm Dew Heater?
Installation is simple. Wrap the heater band around the optical tube, near the front objective lens or corrector plate. Use the integrated Velcro strips to pull it snug for a firm, secure fit that ensures good thermal contact with the tube.
