openFITS - Create Images from Raw Data

With a basic understanding of astronomy data and image processing software, you can create your own astronomy images from FITS files. "FITS," which stands for Flexible Image Transport System, is a digital file format used mainly by astronomers. In this section you can download FITS files for some of our favorite Chandra images and learn how to compose your own versions of these high-energy atronomy images. Please tell us what you think and send an email.
