Improving telescopes, therefore, is about making the tarmac of those mirrors as pondering as imaginable. "Greyish is the most deliberating substantive, but it is meticulous to elaborate with, and it tarnishes and...Source: www.techradar.com
How to Build an Astronomical Telescopebest global publishing. 2007. ISBN: 9781846930430,184693043X. 116 pages.
"The process is described in great detail so that the making of the mirror is an enjoyable and relaxing task. Simple test methods are described so that you do not over grind the mirror but achieve the correct shape. How to simply mount the mirror in a tube is then covered in detail. The result will be a working astronomical telescope capable of viewing the Heavens. Only everyday tools are required throughout"--P. [4 of cover].

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.

Astronomy: The Solar System and BeyondCengage Learning. 2009. ISBN: 9780495562030,0495562033. 512 pages.
With this newly revised 6th edition of ASTRONOMY: THE SOLAR SYSTEM AND BEYOND, Mike Seeds and Dana Backman's goal is to help students use astronomy to understand science and use science to understand what we are. Fascinating and engaging, this text illustrates the scientific method and guides students to answer these fundamental questions: What are we? and How do we know? In discussing the interplay between evidence and hypothesis, the authors provide not just facts, but a conceptual...
