The advent of increasing satellite traffic poses a significant challenge to ground-based astronomical observations, often leading to image contamination due to satellite streaks. Addressing this issue, we introduce 'Blink', an innovative software system designed to predict satellite passes that intersect a telescope's field of view and subsequently activate a fast shutter to prevent image streaking. This paper outlines the development, capabilities, and potential applications of Blink in the realm of observational astronomy. Blink employs sophisticated algorithms to forecast satellite trajectories and their timing relative to a telescope's observational schedule. Upon predicting an imminent satellite pass, the software sends a real-time trigger to a fast-acting shutter system. The software can be augmented by integration with a network of horizon cameras. These cameras serve a dual purpose – they enhance the accuracy of satellite pass predictions and detect unexpected objects, such as space debris, which are not catalogued in standard databases. This real-time monitoring capability significantly improves the reliability of the system.
