Lacerta flat field mask 183mm

A Flatfield Box (FFB) serves the crucial purpose of generating precise flats for astrophotography calibration. It effectively eliminates vignetting, preventing dark edges, and minimizes shadows caused by dust particles on images. This calibration is not just about aesthetics; only flawlessly flat images can be adequately stretched to reveal faint signals, enhancing contrast, removing background speckling, and rendering the faintest object tails visible.

Key Properties of the FFB:

1. Color-Neutral Light: The light emitted is highly color-neutral, ensuring rapid saturation of color channels, ideal for successful flats even with narrow band filters.
2. Uniform Illumination: Offers significantly better uniformity than traditional flatfield generators, minimizing variations across the surface and edges.
3. Flicker-Free LEDs: The LEDs operate at a different frequency from the mains, enabling shorter exposure times without causing a "venetian blind" effect, such as with exposures as short as 1/500 seconds.
4. Optimal Brightness: Emitting only about 10% of the brightness of many other models, ensuring suitability even for highly sensitive CMOS and CCD cameras.
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.
