Ask HN: How to get started with astrophysics

I've been reading a lot of Neil deGrasse Tyson, I watch Sixty Symbols and Deep Sky Videos and since being 10 years old I was interested in space/exploration. Not mentioning all the sci-fi books/movies/games I went over. I feel passionate about it, started my own observations with my first ever telescope (it is great!) and I would like to push it to the next level.

I wonder which books/courses are recommended to start with astrophysics more as a science then ad hoc hobby. I've started the edX program https://www.edx.org/xseries/astrophysics but there might be better resources (especially books as I'm more a reader than a watcher).
