PrimaLuceLab Dew Heater for 50mm Diameter Telescopes
The PrimaLuceLab Dew Heater for 50mm Diameter Telescopes prevents condensation on small optics by applying gentle, consistent warmth, drawing just 330mA from a standard 12V power source. Its elastic design and strong Velcro fastener ensure a secure fit on optical tubes ranging from 40mm to 60mm in diameter, making it an essential tool for finderscopes, guide scopes, and small refractors.
330mA Gentle Heat for 50mm Optics
Dew formation on objective lenses is a persistent issue, especially for sealed optical tubes like refractors and Schmidt-Cassegrains that can't easily equalize with falling ambient temperatures. This heater gently raises the lens temperature just above the dew point, ensuring your view remains clear all night. With a power consumption of only 330mA, it provides effective prevention without significantly draining your field battery.
Secure Fit for 40mm to 60mm Tubes
Designed primarily for 50mm optics, this dew heater incorporates an elastic element that allows it to conform to a range of tube sizes from 40mm to 60mm. The robust Velcro closure provides a strong, uniform grip around the optical tube, ensuring excellent thermal contact without slipping. This adaptability makes it a versatile solution for nearly any finderscope or compact guide scope in your imaging train.
12V RCA Connection for EAGLE Integration
This dew heater is engineered for seamless integration with the PrimaLuceLab EAGLE series of telescope controllers. You can plug it directly into one of the EAGLE's 12V, software-controllable power ports. For observers outside the EAGLE ecosystem, the heater's standard RCA-style connector and 12V requirement make it fully compatible with most third-party dew heater controllers.

How does the PrimaLuceLab 50mm Dew Heater connect to an EAGLE controller?
The heater connects directly to one of the 12V RCA-style power output ports on any PrimaLuceLab EAGLE model. Power to the heater can then be managed and monitored through the EAGLE's control software.
Will this PrimaLuceLab 50mm Dew Heater fit my 60mm guide scope?
Yes. While designed for 50mm optics, the heater has an elastic construction that allows it to fit securely on optical tubes with diameters from 40mm to 60mm. The Velcro fastener will ensure a snug fit on your 60mm guide scope.
What is the power consumption of the PrimaLuceLab 50mm Dew Heater?
The heater has a low power draw of 330mA (0.33A) at 12V. This efficient design provides sufficient heat to prevent dew while minimizing the impact on your field battery's lifespan during an imaging session.
Can I use the PrimaLuceLab 50mm Dew Heater with a non-PrimaLuceLab dew controller?
Yes. The heater uses a standard RCA-style power connector and runs on 12V DC power. It is compatible with any dew controller that provides power through this common connection type.
I have a 50mm finder on my Celestron 8" SCT. Is this the right dew heater for it?
Absolutely. This is the ideal heater for a 50mm finder scope. Both the main optics of an SCT and the smaller optics of a finder are highly susceptible to dew, and keeping both clear is critical for locating and tracking targets.
Why is my PrimaLuceLab 50mm Dew Heater not getting warm?
First, confirm the heater is securely plugged into a 12V power source. If using an EAGLE or other controller, ensure the specific port it's connected to is switched on and configured to provide power. Also, verify that your main power supply has enough amperage to run all your connected equipment.
