Will the PrimaLuceLab Dew Heater fit my Celestron C11 or Meade 10" SCT?
PrimaLuceLab sizes this heater by tube diameter: it fits tubes from 280mm to 300mm in outside diameter. A telescope's tube is wider than its aperture, so measure the outside diameter of your C11 or Meade 10" tube and check it falls within that range.
How do I power the PrimaLuceLab 280mm Dew Heater?
The heater is powered by a 12V DC source and uses a standard RCA-style plug. You can connect it directly to one of the power ports on a PrimaLuceLab EAGLE computer or use any third-party dew controller that has a 12V RCA output.
Can I control the temperature of the PrimaLuceLab Dew Heater?
This dew heater does not have a built-in controller. The heat output is managed by the device it is plugged into. When connected to a PrimaLuceLab EAGLE, you can use the EAGLE Manager software to turn the power port on or off. For variable temperature control, you would need to connect it to a dedicated dew controller with adjustable output.
Is this PrimaLuceLab heater necessary for imaging planets with my 280mm SCT on a humid night?
Absolutely. High-resolution planetary imaging requires stable, clear optics. On humid nights, the corrector plate of an SCT can dew over surprisingly quickly, blurring fine details on Jupiter or Saturn. This dew heater prevents that by keeping the glass just above the dew point, ensuring your view remains sharp for the entire imaging session.
What is the advantage of using this dew heater with a PrimaLuceLab EAGLE?
The primary benefit is system integration and cable management. The EAGLE provides multiple 12V power ports, allowing you to power this dew heater directly from the unit mounted on your telescope. This eliminates the need for a separate dew controller and extra power cables running from the ground up to your optical tube.
How much power does the PrimaLuceLab 280mm heater consume?
The heater has a power consumption of 630mA (0.63 Amps) at 12V. This is a relatively low draw, allowing for extended use in the field with most portable astronomy power supplies without rapid battery depletion.
