Lacerta flat field mask 354mm (67326)

A flatfield box (FFB) is an essential tool for astrophotographers, designed to create flat frames for precise calibration of astrophotos. These flat frames help eliminate vignetting (dark edges) and remove shadows caused by dust particles, ensuring high-quality images. By using a flatfield box, the contrast in your photos is improved, background speckling is reduced, and even the faintest details of celestial objects become visible. This makes it a crucial accessory for achieving professional-level astrophotography results.

Special Properties of the Flatfield Box:

• Color-Neutral Light: Provides an ideal basis for successful flat frames, even with narrowband filters, as the color channels quickly become fully saturated.

• Extremely Uniform Illumination: Offers better consistency than traditional flatfield generators, avoiding faint variations across the surface and edges.

• Flicker-Free LEDs: Operate at a frequency different from mains power, allowing significantly shorter exposure times without creating a "venetian blind" effect (e.g., 1/500 seconds).

• Optimized Brightness: About 10% as bright as other models, making it suitable for highly sensitive CMOS and CCD cameras.

• Innovative Foam Mask Design: Features a round foam mask that securely fits telescope lens tubes. Simply place it on top, push it down, and the lens tube will fit inside snugly.

The flatfield box includes a standard 12V connection (5.5mm/2.1mm jack, center positive) and comes with a vehicle plug (cigarette lighter cable) for added convenience.
