These pages contain the viewgraphs of my lecture on Observational Cosmology, which I taught at the University of Tübingen during the Sommersemester 2005. You should use this link to go to a newer version of these lectures.

The lectures were taught as a compact course from April 18 through 21 (4 days of 4.5 hours of lectures each). The classes were taught in German, however, all viewgraphs are in English.

Feedback concerning errors in these slides is appreciated! You are free to use these slides for your own teaching, however, I would like to hear from you such that I can keep you informed concerning updates of these viewgraphs. Please note also that I keep the copyright on these viewgraphs. I will make the TeX sources to the viewgraphs available upon request such that you can modify them for your use.
