Flat-Field-Box for astro photography
for up to 10" instruments - 290mm clear aperture
The Lacerta flatfield box is used to create flats, which are necessary for the accurate calibration of astrofotos. The vignetting (darker edge) and shadows of dust particles can thus be eliminated. This is not only aesthetically necessary, but only a perfectly flat image can be stretched so strongly that weak signals are visible.
Neutral and extremely uniform illumination
The special feature of the flatfield box is that:- it provides a very color neutral light, so the color channels are equally saturated, and this is the ideal basis for a successful flat.
- Furthermore, the illumination is extremely uniform, even better than the EL films or another FFB, which still have weak variations over the surface
- The LEDs do not flicker in the mains frequency like the EL film, which means that much shorter exposure times can also be used, eg 1 / 100sec.
- The LEDs can be controlled with the optional dimmer or controller, so there is no problem with very sensitive CCD cameras.
