My step into astrophotography and the recent Hubble legacy field got me interested in just how the Hubble images are processed, who processes them, what kind of software is involved etc... However, all that my search has come up with is that the images are mono, many times mosaics, and a touch about assigning colors to channels. This is all very basic information to anyone who is familiar with astrophotography. I would like to read more about the more complex things we deal with in our post processing such as noise, color balance, things of that nature, things that an AP'er might be more interested in rather than someone who may know nothing about astrophotography fundamentals and may simply be wondering whether or not the images from Hubble are taken in color, or with a consumer camera etc... If anyone knows anything about this subject, or can point me to some good reading material please share!
