I've never been too interested in astronomy but telescopes were always pretty cool.
For a book written over 100 years ago, I was surprised at the facts known at that time. It would be interesting to read a current work detailing the facts now juxtaposed to then.
Overall, this was an interesting read. Though dry reading, and much of it went over my head, it was nonetheless informative.
Although I to some extent understood the concept of the Hubble Space Telescope, I now hold a far greater appreciation for it's presence. Now let's just hope that it doesn't get pelted with a cosmic snowball.
