i took astronomy 2 this past summer and am currently enrolled in astronomy 1. i don't attend the class because it moves at too remedial a pace, and i usually have something to do in my lab that would be more productive than watching a man try to explain the doppler effect or retrograde motion to people who do not and may never understand it. The material itself is very interesting, especially in astronomy 2. I have learned a number of new things that I didn't know before taking it. I would highly recommend this course, even if it means skipping your lectures and reading the chapters yourself for the tests.
It would be nice to have mid-level astronomy class available to people who have taken modern physics, but you can't have everything, and not everyone wants to take their science credits that late in their undergrad career
Topics we touched on in the two semesters were characterization of the planets, planetary motion (the concepts, no real math), expansion of the universe, the structures of stars, galaxies, nebulae, dust clouds, and local systems, formation of stars and their evolution and death, evidence supporting the big bang theory, interpretation of spectra and other methods used to range stars, and others
