Book is totally applicable to latest Calculator version the TI-84 Plus CE.
This is a good book if you want to learn how to make good use of your TI 84 plus. I recently bought a new 84 Plus Ce, and this book is entirely valid since the Calculator is more or less still the same, just a newer version. Reason for 3 stars is just the book I received, while quite inexpensive, looks like it was in a wet environment, so it is a bit buckly and wobley, but still readable so I will use it. Thanks.

Very interesting detail information if you like Astronomy and Ephimerides.
Well this book is only useful if you have an interest in astronomy, and particularly in the details where are objects at different times. If you want up to date will need the latest, so an old copy may not be good for you.

Book #2 is the best of the Three
I don't want to build a telescope but like to read about how to do it. This book is one of the best. How to design or make a refractor, how to design and make a Schmidt camera. I read this book many years ago and bought it to bring back old memories. It is still a very relevant book if you want to know how to make a telescope.
