The DewMaster2 from Pegasus Astro is a versatile device designed to manage dew heaters for telescopes and other optical equipment. It supports up to five outputs with individually adjustable power levels, allowing precise control to prevent dew formation. Each channel is protected against overcurrent, ensuring safe operation during extended use. The unit features a robust and compact design, making it suitable for field or observatory use.
The device includes WiFi connectivity, enabling remote management through a dedicated web interface or app. Users can monitor and adjust settings wirelessly, offering convenience during observing sessions. The DewMaster2 integrates advanced temperature and humidity sensing, automatically adjusting output levels based on environmental conditions for optimal performance.
Power for the DewMaster2 is supplied through a 12V DC input, which accommodates standard power sources used in astronomy setups. The unit is equipped with reverse polarity protection and features an LED indicator for operational status, providing reliability and ease of use.
Multiple operating modes are available, allowing users to configure the device for various scenarios. These include manual adjustment, auto-regulation based on sensor data, and presets for specific conditions. This flexibility ensures compatibility with different observing and imaging setups. The DewMaster2 comes with a standard warranty, covering manufacturing defects and providing peace of mind to users.
The DewMaster2 offers enhanced functionality for precise dew heater management. Users can connect up to five dew heaters through independent RCA outputs, each powered by high-capacity MOSFET transistors. These transistors support up to 6 Amps per channel, ensuring reliable and efficient performance without significant voltage drops. Automatic control is made possible by PWM adjustments that reduce battery consumption. With intelligent environmental monitoring, the device adjusts heater levels based on real-time humidity, temperature, and dew point data, effectively preventing moisture buildup.
An external temperature and humidity sensor is included, providing accurate environmental readings. Two additional temperature probe inputs allow precise monitoring of optical components. This setup ensures optimal dew prevention while avoiding unnecessary heat that could interfere with image quality. Users can assign these probes to specific outputs for customized control of their equipment.
The DewMaster2 features flexible control options through USB-C and Wi-Fi. The USB-C connection offers a stable, low-latency experience, while the Wi-Fi functionality allows users to access the device remotely through smartphones, tablets, or computers. The device supports both Wi-Fi Hotspot and Client modes, enabling direct control or integration into a local network. Users can manage all functions via a web browser interface or ASCOM-compatible imaging software, such as NINA, using ASCOM Alpaca and ASCOM 7 drivers.
The unit is built for durability, housed in an aircraft-grade aluminum enclosure with a blue anodized finish. A 2.1-inch red OLED screen provides high-contrast, lag-free display even in extreme temperatures, preserving night vision with its red film overlay. The three-button interface ensures straightforward navigation and quick adjustments.
Additional features include two 12V DC pass-through outputs for powering auxiliary equipment and integrated power monitoring for real-time oversight of voltage and current consumption. The device also supports mounting with the PEG-SHOE attachment for secure positioning during use. With its robust design and advanced capabilities, the DewMaster2 provides efficient and user-friendly dew management for astronomy setups.
