Funny you should mention it, but I just bought the same book this afternoon for the same measly price. I also picked up a large softcover art book called 50 Years in Space: What We Thought We Knew. It collects old paintings from the 50s to the 70s of the planets, stars and other celestial objects and examines how they were created based on the science of the time and how it compares to our knowledge of today. It was also an incredible $2.
