GIOTTO 560mm Smart Flat Field Generator

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.

GIOTTO 560 flat field generator has a maximum illuminated diameter of 560mm: 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.

GIOTTO 560 Smart Flat Field Generator - main features:

• Designed for telescopes with aperture up to 560mm
• LED lights at color temperature similar to sunlight, to provide a neutral color tone
• Special designed light diffuser for an even illumination
• Adjustable light intensity by 100 steps (0 to 100%)
• It natively runs off of a 12V power source to avoid the need for external power units
• USB-C port to let you easily connect it to your EAGLE or Windows computer
• WiFi connectivity so you can wirelessly control it using your smartphone or tablet via the included Virtual HandPad
• Control and capture flat frames with PLAY astrophotography software for EAGLE or Windows
• ASCOM driver to let you control it through third party softwares
• Optional ALTO telescope cover motor to convert GIOTTO in a remotely controlled motorized cap
• Weight: 4.0 kg (8.8 lb)
  

GIOTTO includes electronics for USB or wireless remote control

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.

GIOTTO 560 is designed for telescopes with aperture up to 560mm

Using GIOTTO 560 is very simple: when you want to record your flat frames, you can simply set GIOTTO 560 in front of your telescope. This  version of GIOTTO is not provided with thumbscrews. Differently from the smaller GIOTTO models, central part of GIOTTO 560 is not illuminated since it's used to keep the light diffuser in position. This part is 150mm in diameter and it doesn't create any problem in reflector telescopes with secondary mirror larger than 150mm in diameter but please note that GIOTTO 560 can't be used with refractors since they have no obstruction.

GIOTTO is easy to use and it helps you in recording flat frames

You can control GIOTTO with PLAY astrophotography software that we designed not only to control PrimaLuceLab devices but also to let you do astrophotography in the easiest way. In fact PLAY comes also with a special wizard that allows you to easily record calibration files for your images. And if you want to use your preferred Windows astrophotography software, you can also control GIOTTO by using other softwares thanks to the dedicated ASCOM driver.

Use the Virtual HandPad to control GIOTTO even without a computer

You can even control GIOTTO without a computer by connecting your smartphone or tablet to GIOTTO WiFi network and by using the included Virtual HandPad. Here you can turn the light on and set brightness. You can also save your preferred settings and recall them very easily, for example by saving different values when you use different filters!

Convert it in a remotely controlled motorized cap by adding ALTO telescope cover motor

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! We designed ALTO to be easily connected with our PLUS clamp to any Vixen or Losmandy style dovetail bar that is already present in many telescopes (like SCT, Aplanatic SCT, RCT, etc). If your telescope has a short bar (for example in refractors or newtonians) you can easily add a longer dovetail bar to let you clamp ALTO just above or below the front end of your tube! This design allows you to adjust GIOTTO and ALTO positions to allow an optimal opening and closing of your telescope.

If you are thinking that image calibration and removal of dust and vignetting is a problem only for us modern astrophotographers, it seems like even Giotto, after completing his painting of Halley’s Comet in 1301, had the same problem!

Giotto di Bondone: Italian painter and architect from Florence during the Late Middle Ages

Giotto's masterwork is the decoration of the Scrovegni Chapel, in Padua, which was completed around 1305. When Pope Benedict XI sent a messenger to Giotto, asking him to send a drawing to demonstrate his skill, Giotto drew a red circle so perfect that it seemed as though it was drawn using a pair of compasses and instructed the messenger to send it to the Pope. The messenger departed ill-pleased, believing that he had been made a fool of. The messenger brought other artists' drawings back to the Pope in addition to Giotto's. When the messenger related how he had made the circle without moving his arm and without the aid of compasses the Pope and his courtiers were amazed at how Giotto's skill greatly surpassed all of his contemporaries.
