Pegasus Astro Retractable FlatMaster NEO 120mm
Our new retractable LED flat-field panel delivers a uniform illumination source for telescopes up to 120mm, ensuring high-quality flat-field frames for astrophotography and photometric captures.
Its adjustable lid can be precisely positioned between 0° and 270°, doubling as a protective cover against dust and moisture for your telescope lens.
Crafted from lightweight, aircraft-grade aluminum, the Flatmaster Neo offers a durable and robust design to safeguard your telescope lens.
Dimmable Led Panel
Unlike other panels in the market, the FlatMaster can adjust its brightness from 0 to 100%. Forget sheets of paper between your telescope and the panel. Remote control the brightness of your panel. Store the brightness per filter and immediately retrieve the value you need.
The Flatmaster 150L can go up to very high brightness levels so it can easily support short exposures (2-3 seconds at f/7) with 3nm narrowband imaging filters
Retractable Panel
The panel can be remotely controlled and adjusted between 0° and 270°. To prevent collisions with obstacles, you can set a custom maximum opening angle.
Designed to fit any telescope up to 120mm, FlatMaster Neo features a specialized silicone flange that ensures a light- and dust-proof seal around your optical elements.
Additionally, this flange helps shield the surrounding area (e.g., in shared host observatory) when the LED is illuminated during flat-frame calibration.
One cable operation – Manual button
Only one USB type C cable provides power and control to your panel / lid. A manual button allows you to open and close the lid.
Dew Heater and Sensors
The device panel features an integrated dew heater that actively removes moisture when fully powered, ensuring a dry, dew-free surface. This prevents water droplets from getting trapped between the lid and the telescope lens after closing.
Additionally, a built-in temperature and humidity sensor automatically adjusts the heater based on calculated dew point levels. You can enable or disable this feature as needed or manually set and store the heater’s intensity.
A built-in light sensor further enhances automation by automatically closing the lid at sunrise.
Wi-Fi Control and Standalone Dashboard
The device features built-in Wi-Fi, allowing you to connect and control it either via its own Wi-Fi hotspot or as a client on an existing network.
Its integrated web dashboard is accessible from any mobile application, providing seamless and intuitive control.
ASCOM and ASCOM Alpaca
The device is fully supported out of the box by ASCOM 7 & ASCOM Alpaca.
