About a year ago (November 2011), I started constructing a home-built autoguider, a setup astrophotographers use in imaging galaxies, nebula, and many other deep-space stuff. The setup is no different from what is used by observatories world wide, except that this one was built entirely from scratch. Feel free to browse the details of the project here.
