Processing

Unlike a lot of photographic endeavors, the job in astrophotography is less than half done once you have captured your data. The images are usually made up of many shorter sub-exposures that get calibrated and averaged in some form to produce the initial image ready for processing. In many cases the target is simply not visible in the initial image and a fair amount of processing may be needed to make the target visible.


This page contains links to several of my favorite processing techniques used to produce many of the pictures on other pages of my website. Several are quick pages showing the workflows while others are more detailed papers and presentations. In addition there are several articles that probide some general background information. Links marked with an asterisk are pages on my web site. Those without the asterisk are external websites over which I have no control.
