Pretty easy, overall.
If you are at all interested in space or physics, you should take this course. The lab part of it can be annoying, but generally the class actually has some pretty good information taught by an enthusiastic and excellent professor.
Highlights of the course were actually learning some of the interesting things about space. Lab is actually where I may have learned the most permanent info because I can look up and now I know what some of the major stars/constellations are. Also learned a lot about the solar system and stars and why it is so hard to find another Earth yet so easy to find copies of other planets like Jupiter

Advice for students:
Take lab seriously. Enjoy the main class. Try not to fall asleep; the chairs are really comfortable and its relatively dim lighting.
