The Pillars of Creation

Come together
Each of the four images has geometrical distortions similar to those you see when you look through a magnifying glass. To combine the images of the four different cameras into a single, accurate picture of the nebula, we need to map and remove those distortions. Once we've done so, the four images fit together nicely, giving us this single mosaic image of the Pillars of Creation, showing light coming through the oxygen filter.

Now the picture is beginning to resemble its final self. But who wants those ugly seams? Let's erase them.
