In my most recent post I published a picture of Globular Cluster NGC 6652. In order to do this, I downloaded three pictures from http://www.spacetelescope.org/projects/fits_liberator/datasets/ , then I put them through an application called FITS liberator, which I downloaded from http://www.spacetelescope.org/projects/fits_liberator/download_v301/). Once I’d “liberated” the images in FITS, I opened them in Adobe Photoshop and layered them on top of each other. The next step was to download the “color composite” action for photoshop, which I got from http://www.spacetelescope.org/projects/fits_liberator/downloads_page/ , so that I could alter the colors. Finally, I changed the color of each layer to Red, Green or Blue, depending on the given wave length in the title of each picture. This process is the same as the process used to produce similar colored images of galaxies and nebulae. These images are called Hubble color composite images.
