Calibration is important in astrophotography because results are greatly improved by capturing special calibration frames called flat,
dark and bias and using them during processing. 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. GIOTTO is the smart
flat field generator that helps you capturing flat calibration frames for your astrophotography.
When you choose a flat field generator, we suggest you to choose a model with illuminated panel larger than telescope optics.
Diameter of your telescope external tube should be lower than the flat field generator maximum illuminated diameter.
In the bottom part of GIOTTO you find the control panel with USB-C port to let you easily connect it to your EAGLE or standard Windows
computer. It also comes with WiFi connectivity so you can wirelessly control it using your smartphone or tablet via the included Virtual
HandPad! In order to power GIOTTO, you don't need a separate power unit, since it natively runs off of a 12V power source so it's easy to
power together with your astrophotography telescope.
