This tutorial covers the methods I use for astrophotography with my Canon XSi digital SLR and Celestron CGEM. It is similar to the tutorial I wrote in December of 2007 for digital SLR astrophotography with my Canon 300D. With the exception of the Orion ED80 refractor, I am using all new equipment. I am also using different software for processing the RAW images into a detailed composite photo. Note that there are different ways of going about astrophotograpy with a digital SLR. In fact, there are probably better ways. This tutorial depicts the methods I used for capturing the example images below. I hope you find my new tutorial useful and please feel free to ask questions or add comments in the “Leave a Reply” section at the end of the tutorial.
