GIOTTO 320 Smart Flat Field Generator (PrimaLuceLab, SKU: PLLGIOTTO320 ) is an intelligent calibration panel designed for telescopes with an aperture of up to 320 mm . A set of LEDs with a color close to 5500 K and a precise diffuser guarantee perfectly uniform field illumination, which translates into perfect flat frames. The built-in controller allows you to adjust the brightness in 100 steps (0-100%) via USB-C or Wi-Fi, and the optional ALTO 2 engine transforms the panel into a remote-controlled telescope cover.
