Every step of construction is detailedin photographs and diagrams, and the underlying ideas are carefully explained. As a result of this three-year collaboration between authors David Kriege and Richard Berry, experienced and well-known telescope makers, you now have the opportunity to build a high-performance telescope from 14 inches to 40 inches aperture based on the thoroughly tested designs described in this book. The Dobsonian telescope takes its name from the astronomer/philosopher John Dobson, who introduced the concept of inexpensive, large-aperture telescopes to astronomy. Amateur astronomers at the time were so amazed that a telescope builtfrom simple, inexpensive materials performed so well that they could hardly believe their eyes. As home-built Dobsonians started showing up at star parties across the nation and people saw what Dobsonians could do, the word spread. In just a few years, the Dobsonian revolution swept the world. Since those early telescopes, Dobsonians have improved dramatically. An entire generation of amateur telescope makers contributed their best insights and refinements to Dobson's original design. Today's Dobsonians are larger, lighter,and more precise than ever before. For example, it is possible to build a telescope of 20 inches aperture that is compact enough to transport Language A language of the resource nothing Format The file format, physical medium, or dimensions of the resource Hardcover https://bib.cozmix.cloud/files/original/e4c6c1b55def289e51507a262d65db90.jpg 5a29847b70080d82acf7555fe29f38ca Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

The manufacturer may have guaranteed accuracy to one-quarter wavelength or as diffraction-limited but most telescope users have, at best, only a hazy idea of how to personally verifying such claims. Sure, there are ways to check the accuracy of individual components but for many they are hard to understand or require costly reference optics and other test equipment. Besides, telescope users are interested in the performance of the entire optical train, not just the main optical element. What is really needed is a test that can be used at the observing site, so that all the problems that impact on a telescope's performance can be diagnosed. Isn't there a simpler and more complete way than the complicated shop tests? Yes, the star test is such a method. It uses the entire working telescope. It isnot a poor substitute or a work-around that uses bits and pieces of the optical system. It is the oldest and most sensitive of the optical tests an inspection of the diffraction image itself. Star-test results apply to the complete imaging performance of the telescope. The star test is lightning-fast and requires only a good high-power eyepiece. It tests the telescope for precisely what it was meant to do. Bad or poorly-aligned instruments fail the star test unambiguously. The star test often allows you to correct the optical difficulty immediately in the field, when you might be frantic t Language A language of the resource nothing Format The file format, physical medium, or dimensions of the resource Hardcover https://bib.cozmix.cloud/files/original/17d76fc491945845b1f7eb9bd026d356.jpg e1c588d8a2641488b0b10d90c383d10c Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Amateur Telescope Making offers a variety of designs for telescopes, mounts and drives which are suitable for the home-constructor. The designs range from simple to advanced, but all are within the range of a moderately well-equipped home workshop. Thus each chapter begins with reasons for undertaking the project, then looks at theoretical consideration before finishing with practical instructions and advice. An indication is given as to the skills required for the various projects. Appendices list reputable sources of (mail order) materials and components. The telescopes and mounts range from "shoestring" (very cheap) instruments to specialist devices that are unavailable commercially.</p> Language A language of the resource nothing Format The file format, physical medium, or dimensions of the resource Paperback https://bib.cozmix.cloud/files/original/fdee2c516c655a7151758c443f994ac7.jpg 086ff355b13b30e1bc455c8ca40c81af Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.
