Celestron EdgeHD 9.25 Flap Panel (FP2)

FP2 PRO XL Motorized Flat Panel

Flat-frame acquisition should be simple, reliable, and easy to automate. The FP2 PRO XL motorized flat panel is designed to make flats a seamless part of your imaging workflow, without improvised solutions such as LCD screens, T-shirts, or the morning sky.

During imaging, the panel stays neatly parked alongside the telescope tube. When your session is finished, simply close the panel and switch on the dimmable LED light to capture flat frames. Brightness can be adjusted to match your camera settings, gain, and filters for consistent results across different setups.

To improve reliability in humid conditions, a dew heater behind the LED panel is now included free with all of our motorized flat panels. It helps remove moisture from the LED surface and reduces the risk of dew being trapped against the OTA when the panel is closed after the session.

The new FP2 PRO XL generation is designed for larger telescopes and brings a number of practical improvements based on customer feedback. It is intended for 8″ to 11″ telescopes and features a much stronger motor and a wider compression ring for improved stability and support on larger optical tubes. It also includes improved sealing performance, improved hinge design, compression rings customized for your telescope with improved design and swappable inserts, and advanced convenience features such as custom open position and integrated obstacle detection.

Combined with upgraded electronics and advanced control features, the FP2 PRO XL is built to deliver a cleaner, more reliable, and more convenient flat-frame workflow for larger imaging systems. We also plan to expand the XL lineup further in the future with units for 14″ to 16″ telescopes.

Whether you are building a fully automated imaging setup or simply want a more elegant way to capture flats on a larger telescope, the FP2 PRO XL is designed to make your routine faster, easier, and more dependable.
