Calibration (darks, flats, bias), star detection, sub-pixel registration, sigma-clipped stacking, background gradient removal — with a focus on speed (SIMD, OpenCL) and reproducible results.\nRepository: github.com/emruiz81/AfterNight The Building AfterNight series explains each algorithm with code and measurements.
