Processing by the pros.
Here's a new image-processing program for astrophotographers by astrophotographers. Pleiades Astrophoto's PixInsight LE includes a comprehensive set of fundamental image-processing tools and advanced resources needed for astrophotography. Examples include Curves, Selective Gaussian Blur Noise Reduction (SGBNR), and the new Dynamic Background Extraction (DBE) process. DBE is a powerful interactive tool for correcting uneven field illumination and color in deep-sky astro-photographs. Intended as an introductory preview to the full edition that will be released in the near future, PixInsight LE is currently available as a free download for PC users running Microsoft Windows 98SE, 2000, or XP.
