Commercially-made astronomical telescopes are better and less expensive
than ever before, and their optical and mechanical performance can be
superb. When a good-quality telescope fails to perform as well as it
might, the reason is quite probably that it needs a little care and
attention! Here is a complete guide for anyone who wants to understand
more than just the basics of astronomical telescopes and accessories,
and how to maintain them in the peak of condition. The latest on safely
adjusting, cleaning, and maintaining your equipment is combined with
thoroughly updated methods from the old masters. Here, too, are details
of choosing new and used optics and accessories, along with enhancements
you can make to extend their versatility and useful lifetime. This book
is for you. Really. Looking after an astronomical telescope isn't only
for the experts - although there some things that only an expert should
attempt - and every serious amateur astronomer will find invaluable
information here, gleaned from Barlow Pepin's many years' experience
working with optical instruments.
