GIOTTO 285 Smart Flat Field Generator (PrimaLuceLab, SKU: PLLGIOTTO285 ) is an intelligent calibration panel designed for telescopes with an aperture of up to 285 mm . The use of white LEDs (approx. 5500 K) and a precision diffuser ensures uniform field illumination, thanks to which you will make perfect flat frames for color and monochrome cameras. The built-in controller allows you to adjust the brightness in 100 steps (0-100%) via USB-C or Wi-Fi, and after equipping with the ALTO 2 engine, the panel can act as a remotely controlled telescope cover.
