Query: Choosing and Using as Schmidt-Cassegrain Telescope

The author provides a complete review of SCT and Makstovs covering all the basics of operation. The chapters on setup, testing and observing are much clearer then the manuals that come with a new scope. If you are considering spending a $1000+ on a new scope you should get this book first. The section on "keeping Your Cat Happy" shows ways to improve your scope's operation without spending a lot. This is stuff that works from dew shields to warning lights. The only limit I have seen in the book is that the goto technology described is changing yet again with new scopes. Celestron has just introduced units with a built in GPS & electronic compasses that find their own location and time. I am sure that Meade can not far behind in introducing their own version. Exploring the stars with SCTs has never been easier, but don't start the trip without this book.
