GIOTTO 220 flat screen

GIOTTO from PrimaLuceLab

Visit GIOTTO from PrimaLuceLab is an intelligent flat-field display designed to produce uniform, precise lighting, essential for capturing flat-field images in astrophotography. These images correct optical defects such as vignetting, dust on the sensor or light irregularities, guaranteeing optimal calibration. Each GIOTTO model is adapted to a maximum mirror or lens diameter, while being compatible with a precise range of external optical tube diameters.

Advanced technical features

• Homogeneous LED lighting Uniform light with a temperature similar to that of the sun, ideal for calibrating CMOS or CCD sensors.
• Adjustable intensity Precise control on 100 levels (from 0% to 100%), adaptable to different filters or optical configurations.
• Modern connectivity integrated WiFi for wireless control via smartphone or tablet, and USB-C port for easy connection to a PC or EAGLE system.
• ALTO compatibility (optional) Turn the GIOTTO into a motorized hood to protect your telescope and automate opening/closing.
