These pages contain the viewgraphs of my lecture on Observational Cosmology, which I am currently teaching at the University of Erlangen-Nuremberg. The classes were taught in German, however, all viewgraphs are in English and handouts of all viewgraphs were given out.

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.
