Pegasus Astro DewMaster

DewMaster was made for the visual astronomer.

Connect up to five dew heaters and control them individually using the PWM duty cycle.

Full digital operation and a high-resolution red film display make control of the device quick and straightforward. See consumed Amperes and Input voltage at a glance.

Combine with an optional external temperature and humidity sensor to know relative humidity, temperature and dew point levels.

Automatic dew heaters control lets you relax, knowing your optics will be moisture free. 


  • Five Channel RCA Outputs for Dew Heaters
  • Pulse Width Modulation (PWM) Duty Cycle Control with Automatic Dew Control
  • Full Digital Operation
  • Easy to Use
  • Red Film LED Display
  • Reverse Polarity Protected
  • Two pass-through DC Outputs with Amp-Meter Showing Current Consumption

Red Film LED Display

A 128 x 64-pixel Organic LED (red film) screen is used for the device.

This display works lag-free at very low temperatures.

The red film on top of the display ensures your night vision is unaffected.
On the left, images show the on-screen display menus of the DewMaster.

External Environment Sensor ( * Included)

An external one (1) meter high-resolution temperature & relative humidity calibrated sensor will let you know the environmental conditions of your site. The sensor can be auto-combined with the dew heater outlets to adjust power levels automatically.

Leave it to the DewMaster to decide whether to turn on your heating elements! You can also monitor temperature, humidity, and dew point readings on the display screen.

* Environmental sensor is now included in the package at no extra cost – Please note that the new sensor is in blue and is compatible with newer firmware only.

Two pass-through DC outputs and an Amp-meter

Two 12V DC outputs let you connect additional equipment with fewer and shorter cables.

The device includes an Amp-meter, which displays the total current consumption of the device, DC outputs, and dew heater channels.
