This is changing! Many people appreciate the relative comfort of two-eyed observing, but those who use binoculars come to realize that they offer more than comfort. The view of the stars is more aesthetically pleasing and therefore binocular observers tend to observe more frequently and for longer periods. Binocular Astronomy, 2nd Edition, extends its coverage of small and medium binoculars to large and giant (i.e., up to 300mm aperture) binoculars and also binoviewers, which brings the work into the realm of serious observing instruments. Additionally, it goes far deeper into the varying optical characteristics of binoculars, giving newcomers and advanced astronomers the information needed to make informed choices on purchasing a pair. It also covers relevant aspects of the physiology of binocular (as in ?both eyes?) observation. The first edition of this title was praised for its suggested objects for observation and especially for the finder charts for each object. In this second edition, this section is expanded in three ways. There are new objects, more information on each object, and a re-organization of the objects for binoculars for easier selection.  Binocular Astronomy 2nd Edition puts an emphasis on understanding binoculars and their use. The additional content reflects the latest developments in technology, new testing techniques, and practical ideas for binocular use. It also responds to the substantially positive reviews of the first edition, and is now even better suited to its target readership. 410 0$aThe Patrick Moore Practical Astronomy Series,$x1431-9756 606 $aConstellations$vObservers' manuals 606 $aConstellations$vAmateurs' manuals 606 $aAstronomy$vObservers' manuals 606 $aAstronomy$vAmateurs' manuals 606 $aBinoculars 615 0$aConstellations 615 0$aConstellations 615 0$aAstronomy 615 0$aAstronomy 615 0$aBinoculars. 676 $a520 676 $a522 700 $aTonkin$b Stephen F.$f1950-$01763270 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910300398203321 996 $aBinocular astronomy$94203629 997 $aUNINA
