This books is sheer nostalgia although I suspect its wasn't meant that way. Let me explain.
This book reminds me of the days before powerful telescopes and computer rendering - this was back in the days when astronomy was vague and tricky to understand and really the domain for the gifted. This was the age when if you wanted to portray something you commissioned an artist.
And this is the book you got. A series of amazing and lavish images of both real (at least how the scientists explained it) and imaginary worlds both near, so to speak and far. If you look carefully you can see the canvas, the brush strokes and the time and effort that was put in to it.
Many of the images here I have seen time and time again though never really acknowledging them or even realising the effort that went in to them and more importantly what the represent to the people who commissioned them.
If you remember the glory days of unexplored heavens this book is a real gem - and I am just glad that there is still room in a world of computer generated spectacles that there is still room for this.
