Pegasus Astro FlatMaster Neo 120 Retractable LED Flat-Field Panel

The FlatMaster Neo 120 is the “make flats painless” upgrade your imaging workflow deserves. It’s a retractable, remotely controlled LED flat panel that delivers uniform illumination for telescopes up to 120mm, with true 0–100% dimming so you can hit consistent exposures without stacking paper, T-shirts, or prayers between the scope and the panel. It’s also built to live on the telescope: the adjustable lid doubles as a protective cover against dust and moisture, and the whole unit is housed in aircraft-grade aluminum for serious durability.

• Uniform flat-field illumination for telescopes up to 120mm (great for calibration and photometric captures)

• True 0–100% brightness control

  • Store brightness per filter and instantly recall the right setting

  • Supports high brightness for short flat exposures (example: 2–3 seconds at f/7 even with 3nm narrowband filters)

• Retractable servo lid (0°–270°)

  • Remote-controlled opening/closing

  • Set a custom maximum opening angle to avoid collisions in tight observatory setups

  • Lid doubles as a dust/moisture cover for your objective when closed

• Specialized silicone flange

  • Creates a light- and dust-proof seal around optical elements

  • Helps prevent LED spill into surrounding areas (useful in shared observatories)

• One-cable operation (USB-C) for both power and control

  • Manual button for open/close and quick control when you’re at the scope

• Built-in dew heater + smart sensors

  • Heater helps keep the panel dry and reduces moisture trapped when closing the lid

  • Temperature + humidity sensor calculates dew point and can auto-adjust heater intensity

  • Option to enable/disable automation or manually set and store heater power

• Built-in light sensor automatically closes the lid at sunrise

• Wi-Fi control + standalone web dashboard

  • Connect via the device’s Wi-Fi hotspot or join an existing network as a client

  • Control from any phone/tablet/computer through the integrated dashboard

• ASCOM 7 + ASCOM Alpaca support out of the box for easy automation/integration
