  • Pegasus Astro Flatmaster Neo 120 mm

    The Pegasus Astro Flatmaster Neo 120 is an automated calibration and protection system for telescopes, providing a perfectly uniform illuminated circle of 120mm. Its LED panel is fully dimmable from 0-100% to precisely match exposure needs for any filter. The entire unit is housed in a robust aircraft-grade aluminum frame measuring 195 x 210 x 95 mm, powered by a single 5V DC USB-C cable.

    A 120mm Uniform & Dimmable Flat-Field Source

    The Flatmaster Neo generates a flawlessly even field of light across its 120mm usable diameter, essential for professional-grade astrophotography and photometry. Unlike panels with fixed brightness levels, the Neo's LEDs can be adjusted from 0 to 100%, allowing you to set the perfect illumination for any filter without adding stacked paper or other diffusion materials. This precise control means you can achieve ideal ADU targets for LRGB filters and still have enough power for short 2-3 second exposures with 3nm narrowband filters.

    Retractable 270° Servo Lid & Dust Cover

    More than just a flat panel, the Flatmaster Neo functions as an intelligent, automated lens cap. The servo-driven lid can be programmed to open anywhere from 0° to 270°, allowing you to set a custom maximum angle to avoid collisions with your mount or other equipment. When closed, it protects your telescope's objective from dust and moisture, and a specialized silicone flange creates a light-proof seal, preventing stray light from escaping during calibration in a shared observatory.

    Integrated Dew Heater with 2 Environmental Sensors

    Engineered for unattended remote operation, the Flatmaster Neo features an integrated dew heater on the panel's surface. A built-in temperature and humidity sensor allows the device to calculate the current dew point and automatically apply power to the heater, preventing moisture from forming. This ensures the panel surface is always dry, so no water gets trapped between the lid and your telescope lens when it closes. A third light sensor can automatically trigger the lid to close at sunrise, securing your optics for the day.

    Full Remote Control: Wi-Fi, Web Dashboard, and ASCOM Alpaca

    The Flatmaster Neo requires only a single 5V USB-C cable for both power and control, simplifying your cable management. It has built-in Wi-Fi, allowing it to act as its own access point or connect to your existing observatory network. Control is managed through a web dashboard accessible from any browser on any device—no PC required. For integrated observatory control, the device offers out-of-the-box support for ASCOM7 and ASCOM Alpaca, making it a seamless addition to any automated imaging sequence.

  • How do I power the Flatmaster Neo 120?

    The Flatmaster Neo 120 is powered and controlled by a single 5V DC USB-C cable.

    Will the Flatmaster Neo 120 fit my 115mm refractor?

    Yes. The Flatmaster Neo 120 is designed to provide a uniform illuminated circle for any telescope with an objective or front aperture up to 120mm in diameter. Its silicone flange seals on telescope hoods from 125mm external diameter up to 166mm internal diameter, and it straps to the hood with the included belts.

    Can I control the brightness of the Flatmaster Neo 120 for narrowband filters?

    Absolutely. The panel is fully dimmable from 0-100%. This allows you to set a low brightness for sensitive LRGB filters and a very high brightness for narrowband filters (like H-alpha or OIII) to achieve a good flat frame with short exposures.

    How does the automatic dew heater on the Flatmaster Neo 120 work?

    The device has built-in temperature and humidity sensors that constantly monitor ambient conditions. From this data, it calculates the dew point and automatically applies power to the integrated heater on the panel's surface to keep it just above the dew point, ensuring it remains free of moisture.

    Do I need a computer connected to use the Flatmaster Neo 120?

    No. The Flatmaster Neo 120 has built-in Wi-Fi and hosts its own web dashboard. You can connect to it directly from a smartphone, tablet, or computer and control all its functions through a web browser without needing to install any software.

    What happens if the Flatmaster Neo 120's lid might hit my telescope mount when opening?

    You can set a custom maximum opening angle. The servo motor allows the lid to retract anywhere from 0° to 270°. If there's an obstruction, you can program the lid to stop at a safe angle, such as 180° (straight up), to prevent any collisions.
