In other words, they blue-shifted the image back into the visible spectrum, which I'm sure would do a decent job of counteracting at least some of the extreme red-shift you get from observing such distant objects.
Whether they actually tried to calibrate the blue-shifting (e.g. by looking for emission spectra), I don't know, but I'm sure it wouldn't be out of the question.
