The GIOTTO 185 Smart Flat Field Generator (PrimaLuceLab, SKU: PLLGIOTTO185 ) is a small, intelligent calibration panel designed for telescopes with an aperture of up to 185 mm . A set of white LEDs (≈ 5500 K) and a high-quality diffuser guarantee completely uniform field illumination, which allows for obtaining perfect flat frames for color and monochrome cameras. The built-in controller allows for brightness adjustment in 100 steps (0-100%) via USB-C or Wi-Fi, and after equipping with the ALTO 1 engine, the panel can act as a remote-controlled telescope cover.
