Calibration

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 if you want to automate the capture of your calibration files or if you're searching for the best way to remotely open and close your telescope, you can add the optional ALTO telescope cover motor and use GIOTTO as a remotely controlled motorized cap!
