➡️ Go to the web app: https://yymao.github.io/decals-image-list-tool/
This web app displays image cutouts for a list of sky coordinates, and allows you to inspect and mark selections on the images. It is similar to the SDSS Image List Tool, but specifically designed for target selection and inspection.
The image cutouts are retrieved from the DESI Legacy Imaging Surveys Sky Viewer (which also includes WISE, GALEX, DES, SDSS, HSC, etc.), the Sloan Digital Sky Surveys (SDSS), and the STScI Digitized Sky Survey (DSS).
