For those who are interested, I placed up an example of the benefit of stacking (combining) multiple images of the same deep sky object. Stacking images allows you to increase your signal/noise ratio, and the combined data allows you to process the image more aggressively to bring out fainter details of the object you're photographing.
Take a look at the following page. Just roll your cursor in and out of the photo on the screen, and it will blink between two images. The initial image is a RAW file right out of the digital camera (Canon D60). The rollover image is the result of stacking 10 of these RAW images, and then doing a bit more image processing. (Note: images are large, give them several seconds to load):
