Comparison of the image cutouts obtained by applying the methodology described in this paper to data from the DESI Legacy Imaging Surveys (top panels) versus long exposure times (6–10 h) images obtained with amateur robotic telescopes from the Stellar Tidal Stream Survey (Martínez-Delgado 2019, bottom panels): our new Stellar Stream Legacy Survey is well positioned to uncover hundreds of low surface brightness features in the local Universe.
