High-precision Astrometry of Saturnian Major Satellites: Halo Reduction and Optical Filter Evaluation

High-precision astrometry of planetary satellites is important for refining ephemerides and supporting deep-space exploration missions. We apply the Bilateral-filtered Single-Scale Retinex with Gaussian regularization (BSSR-Gaussian) method to 140 CCD images of Saturn obtained at Yunnan Observatory and evaluate the p...
