ASCOM Flat Panel Buddy

The ASCOM Astro Flat Panel Buddy, model AFP-X, is a dedicated solution for astronomers and astrophotographers seeking automated control over flat field calibration exposures. Designed and distributed by Astro-Smart, this system has been developed to offer seamless operation with a wide range of astronomical imaging software and telescope configurations. It provides precise control over the brightness level of flat panels, ensuring consistent and accurate calibration of images regardless of gain settings or the type of telescope in use.

At the core of the AFP-X is its compatibility with the ASCOM platform, which allows users to control flat panel brightness via software such as NINA and Sequence Generator Pro. This means the unit is fully automated when integrated into an imaging workflow, letting the software determine and apply the exact brightness levels required for capturing flat field frames. Flat frames are essential in astrophotography as they help eliminate optical imperfections such as dust motes, vignetting, and uneven field illumination. The AFP-X handles these corrections by enabling controlled illumination of flat panels to match the ADU targets required by the camera's gain and full well depth.

The AFP-X supports two voltage levels, 5V and 3.3V, providing flexibility across a range of flat panel types and telescope systems. Users can set the correct voltage with a hardware switch, which includes three positions. The left position activates 5V operation, the right is for 3.3V, and the center position turns the flat panel off, making it suitable for capturing dark frames when needed. This small but important feature gives the AFP-X a dual utility function that supports both flats and darks in one compact system.

The desired outcome of flat frame calibration is to match the exposure to approximately 25 percent of the camera sensor's full well capacity. The AFP-X enables this by allowing fine adjustments to the panel's brightness level. For example, a camera operating at zero gain may have a full well capacity of 65,000 ADU, meaning the ideal flat exposure should be around 16,000 ADU. When gain is increased, full well capacity is reduced. At gain 100, the full well might be 25,000 ADU, requiring flats to be captured at around 6,000 ADU for accurate calibration. The AFP-X offers the control necessary to dial in these values precisely.

One of the key benefits of this system is its seamless integration with software such as the NINA flat panel wizard. This feature allows the telescope to automatically slew to the zenith position, simplifying the placement of the flat panel over the aperture. Once positioned, NINA takes control through the ASCOM driver and adjusts the flat panel brightness in real-time to match the desired ADU value. This process removes the guesswork and manual intervention from flat frame calibration, speeding up the imaging setup and reducing human error.

The AFP-X unit is not tied to a specific type or brand of telescope. Whether the user operates a refractor, Newtonian reflector, Schmidt-Cassegrain, or Ritchey-Chrétien telescope, the system is designed to adapt. This versatility is further enhanced by a range of available flat panel sizes. Astro-Smart offers round panels in 4-inch, 6-inch, 9-inch, 10-inch, 12-inch, 14-inch, and 16-inch diameters. For users requiring custom configurations or rectangular panels, special orders can be requested. This makes the system scalable for everything from small portable rigs to large observatory-class telescopes.

The flat panels themselves are designed to emit uniform illumination across their surface, a requirement for consistent flat field results. The brightness control of the AFP-X is pulse-width modulated and offers up to 255 intensity levels, giving users fine granularity when tuning brightness output to match their imaging requirements. Since exposure levels for flats vary depending on optical configuration, filter use, and sensor characteristics, this wide adjustment range is essential for matching many different setups.

Connectivity between the AFP-X and the computer is managed through a USB-C to USB-A cable, which is supplied with the unit in a 10-foot length. Users can substitute cables of different lengths to suit observatory layouts or portable setups. The system relies on standard USB power and communication protocols, ensuring easy compatibility with modern laptops and imaging control systems. The choice of USB-C reflects a forward-thinking design philosophy that emphasizes durability and ease of use.

Astro-Smart highlights the long development cycle of the AFP-X as a key reason for its reliability and performance. The company’s experience in astronomy equipment design helped identify and overcome many of the common limitations found in competing flat panel controllers. These lessons were applied to ensure the AFP-X would be robust, intuitive, and durable under real-world conditions. Each unit is reportedly subjected to burn-in testing before shipping to guarantee functionality and quality.

The device is backed by a worry-free warranty program that remains in effect for the life of the product while offered for sale. This commitment to support is part of Astro-Smart’s broader philosophy of creating user-friendly, serviceable, and elegant products that meet the needs of amateur and professional astronomers alike. The AFP-X design emphasizes simplicity in operation, with no need for excessive cables, external power supplies, or complicated setup steps. Its core interface is lean but powerful, focused on what is essential for calibration workflow integration.

The software support extends beyond NINA. The AFP-X can be used with any application that supports the ASCOM flat panel interface, including Sequence Generator Pro and Astro Photography Tool (APT). The drivers are readily available and designed to work with third-party applications without custom configuration. This maximizes compatibility across the wide variety of imaging environments used by astronomers today.
