Here are some image processing examples using data taken with an Optical Guidance Systems 32" Ritchey-Chretien scope and SBIG STL-11000m CCD Camera. The examples include links to download the raw data files. To execute the same processes you will need CCDSharp (Free), MaxIm DL (Not Free), and Photoshop (Not Free). The raw files are in FITS form, and are 20mb each (4 or 5 files per example).

You can, of course, just browse the example without any software or downloads to review the techniques employed.
