Portability is important for almost every deep-sky observer today. Rarely do we have a home observatory with dark skies. We must travel to view the splendours of the night sky. Weight, ease of setup, steadiness and observer comfort become critical in whether the experience is enjoyable and sustainable.
Prior to this new book, most of that knowledge did not exist. Learn how to
- distinguish between the two classes of string telescope substructures
- predict deflections of complete telescope optical assemblies and select the appropriate configuration of struts and guy wires (strings) for your project
- construct, evaluate, and properly tension guy wires made from steel cables or bowstring yarn
- measure and analyse the vibrations of any telescope structure
Building a telescope using flexible structural elements is generally a more ambitious project than one employing only rigid struts. Readers can tackle the project with confidence, knowing that the author has fully explained the underlying science and engineering of string telescopes. The answers to the most probing technical questions can be found here. Yet, little or no technical training is required to build a satisfying instrument. Readers can base their telescope on one of the two successful examples. Their lengthy chapters, profuse with drawings and images, and extensive construction detail, will lead you through the steps required to build an attractive telescope that meets exacting goals.
