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.

Presents 200 hitherto unpub. astronomical texts & horoscopes written in Greek on papyrus, which were excavated a century ago in the rubbish heaps of Oxyrhynchus, a district capital of Roman Egypt. Through these documents we obtain the first coherent picture of the range of astronomical activity, chiefly in the service of astrology, during the Roman Empire. The astronomy of this period turns out to have been much more varied than we previously thought, with Babylonian arithmetical methods of prediction coexisting with tables based on geometrical models of orbits. Editions of the texts are accomp. by facing translations & explanatory & philological commentaries. The intro. provides the first comprehensive treatment of astronomical papyri, explaining their contents & purpose, the underlying astronomical theories, & strategies for analyzing & dating them. Tables & graphs.

Small and large telescopes are being installed all around the world. Astronomers have thus acquired better access to more modern equipment; not in the least to photometers, which are very important tools for the contemporary observer. This development of higher quality and more sensitive equipment makes it very necessary to improve the accuracy of the measurements. This guide helps the astronomer and astronomy student to improve the quality of their photometric measurements and to extract a maximum of information from their observations. The book is based on the authors' observing experience, spending numerious nights behind various instruments at many different observatories.
