GIOTTO is the smart flat field generator we designed to help you capture flat calibration frames for your astrophotography! Astrophotography results are greatly improved by image calibration that uses special calibration frames called flats, darks and bias. In particular, flat frames are recorded by pointing your telescope at a white surface and it allows to mitigate effect of vignetting and shadows created by dust on the optical system. And it seems like even Giotto, after completing his painting of Halley’s Comet in 1301, had the same problem we face today!
