IRSA provides a convenient finder chart tool at https://irsa.ipac.caltech.edu/applications/finderchart/ that yields images from DSS, 2MASS, WISE, Spitzer, SDSS, AKARI, and IRAS. The tool accepts single input or tables.

We have developed a simple script (keck2irsa) to convert Keck-formatted starlists into the IRSA table format. This allows users to create finder charts for their list. The original version of the finder chart tool was limited to 50 targets, but this is no longer a restriction.
