Lacerta flat field mask 283mm

The Flatfield Box (FFB) is essential for achieving precise calibration of astrophotos, ensuring the elimination of vignetting and shadowing caused by dust particles. This not only enhances aesthetics but also enables the stretching of perfect "flat" images, making faint signals visible. Here are some key features of the FFB:

1. Color-Neutral Light: The FFB emits highly color-neutral light, facilitating rapid saturation of color channels for successful flats, even with narrow band filters.
2. Uniform Illumination: Unlike traditional flatfield generators, the FFB provides extremely uniform illumination across the entire surface and edge, minimizing variations.
3. Flicker-Free LEDs: Operating at a different frequency from the mains, the LEDs allow for significantly shorter exposure times (e.g., 1/500 seconds) without causing a "venetian blind" effect.
4. Optimal Brightness: Emitting only about 10% of the brightness of many other models, the FFB ensures it is not too bright for highly sensitive CMOS and CCD cameras, preserving image quality.
5. Innovative Foam Mask: The round foam mask ensures a secure fit on compatible telescope lens tubes. Simply place it on top, push down, and the lens tube effortlessly slides inside.

The flatfield boxes feature a standard 12V connection (5.5mm/2.1mm jack, center positive) and come with a vehicle plug (cigarette lighter cable) for convenient power access.
