-    "This tutorial demonstrates the use of `astropy.utils.data` to download a data file, then uses `astropy.io.fits` to open the file, and lastly uses `matplotlib` to view the image with different color scales and stretches and to make histrograms. In this tutorial we've also included a demonstration of simple image stacking."
