Binoscopes can be thought of as binoculars enlarged to the size of telescopes - essentially, a combination of the two.  Constructing a binoscope is easier than most people think, but it still demands attention to detail and proper background knowledge. The author goes on to provide additional information about the products currently on the market, should the reader choose to purchase one instead of building it. Lastly, the book also compares binoscopes with telescopes in great detail, outlining the differences the reader can expect to see in the night sky from using both. The celestial views obtained with a binoscope, compared to a single telescope of the same aperture, are a very different experience. The new edition emphasizes the obvious advantages of viewing celestial objects through a binoscope. There are also many new photos and additional information on the latest equipment and some very special and rare equipment a collector might be interested inches Newly added cartoons and additional images of beautiful deep sky objects in each of the chapters makes reading the book a more enjoyable experience. Finally, there is a new comet discovery form and guide to follow for such discoveries, and a complete list of Messier objects for those interested in searching for these.  aDescription based on publisher-supplied MARC data. 0aAstronomy.96849 0aAstronomy-Observations.931398 0aObservations, Astronomical.93139908iPrint version:tBuilding and using binoscopesz9783319467887w(DLC)  201793081408iPrinted edition:z978331946788708iPrinted edition:z9783319467900 0aThe Patrick Moore Practical Astronomy Series,x1431-9756931400  2lcccBK  00102lcc4070aCPLbCPLcCARTd2021-12-16g3069.00l0oQB 88 .B8 2017p2021/56715r2021-12-16 00:00:00w2021-12-16yBK
