Advanced Image Processing
Once you have mastered the taking of images, it's time to start applying more powerful and also more subtle image processing techniques. A good image is good because it has low noise and lots of data to work with. This allows you to go a little further toward that elusive "perfect image" by applying the advanced techniques you will learn in this chapter. Whether the subject is a distant quasar, dim Bok Globules in the Orion Nebula, or simply an ultra-sharp image of the moon, this chapter will help you take your images to the next level.

This ultra-sharp image of the moon was made possible by a combination of
a very high-quality image through an APO refractor (Takahashi FC-125)
and careful processing to sharpen the image even further in Maxim/DL and Photoshop.
