The Hatfield SCT Lunar Atlas: Photographic Atlas for Meade, Celestron and other SCT Telescopes

The Hatfield SCT Lunar Atlas: Photographic Atlas for Meade, Celestron and other SCT Telescopes by Jeremy Cook
English | PDF (True) | 2005 | 129 Pages | ISBN : 1849969035 | 14 MB

SCT and Maksutov telescopes - which of course includes the best-selling models from Meade, Celestron, and other important manufacturers - reverse the visual image left for right, giving a "mirror image". This makes it extremely difficult to identify lunar features at the eyepiece of one of these instruments using conventional atlases, which show the Moon "upside-down" with south at the top.

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.
