DarkLight Cover/Calibrator
DIY project to build a cover, flat panel or combo flip-flat panel
The DarkLight Cover/Calibrator (DLC) is a DIY project to build a motorized telescope cover, flat panel, or a combination flip-flat system. Its modular design supports various setups: a 12V light panel without a servo for a wall-mounted calibration panel, a servo-only cover for sky flats, or both integrated into a flip-flat mechanism. The DLC also includes optional dew heating to reduce extra equipment and cabling. With available drivers, it works with ASCOM or INDI. We’re excited to... -
