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 are 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.
Lots of information in here, though I find that there is much repetition within the books of this series. I would have liked to see this be much shorter, with the sections primarily on “Care of astronomical instruments” being the bulk. It’s certainly a useful book, but when pulling a specific title from this series for niche information I expect to have a focused look at only that information.
Maybe my qualms are with the series, not the book itself.
