What software is available for astronomical image processing?
Image processing software is used to manipulate the data held in a digital image. In astronomy this is typically applied to digital camera images, ccd-images and (less common) scanned photographs and slides. There are many different packages available. In addition to general image-processing software like Adobe PhotoShop® and Paint Shop Pro®, there is dedicated astronomical image-processing software. Most CCD cameras come with some image-processing software.
