If you want to undertake an astronomy course but not concerned about getting the formal recognition, then Berkeley University USA offers this course online by Alex Filipenko - and its free.

I have just completed all the classes and have greatly increased my knowledge and interest in astronomy and cosmology. Although it is the 2007 course it is still very good and worth the time. Could even be used as a precursor to a full time course.
